From b4c7d64400dc4fa4e66621c529ba01a71473d839 Mon Sep 17 00:00:00 2001 From: octalpixel Date: Wed, 1 Jul 2026 12:50:33 +0530 Subject: [PATCH 01/14] =?UTF-8?q?feat(server,core):=20enrichment-accuracy?= =?UTF-8?q?=20eval=20=E2=80=94=20matcher.evaluateEnrichment=20+=20fashion.?= =?UTF-8?q?evalAttributes?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the loop named as samesake's make-or-break risk: search relevance was measured (evaluateSearch), enrichment correctness was not. A mis-extracted color or missed neckline only shows up in search as blurred noise; this measures the root cause — the enrichment twin of evaluateSearch. Framework (baked in, no stubs, generic): - packages/server/src/core/evaluate-enrich.ts — pure scoreEnrichment() (per-attribute TP/FP/FN -> precision/recall/F1, micro+macro, coverage, per-product diffs) + makeEvaluateEnrichService reading enriched rows; wired onto matcher.evaluateEnrichment and exported from @samesake/server. - packages/sdk/src/templates/fashion.ts — fashion.evalAttributes() default attribute spec, alongside fashion.fields/spaces/nlq. Harness + data (example, mirrors eval.ts + golden-queries): - examples/fashion-search/eval-enrichment.ts — runner (--fixture offline / live / --bootstrap), consuming fashion.evalAttributes() + matcher.evaluateEnrichment (nothing hand-rolled). - evals/golden-enrichment-fashion-lk.json — 50 real LK products labeled from titles (enum-validated). - evals/fixtures/enrichment-demo-store-predicted.json — captured pipeline output for offline scoring. Baseline on the 50-product demo_store LK corpus (live == offline): micro F1 97.8%, macro 98.2% (category 94, gender 100, colors 99, pattern 100, is_apparel 98). The run surfaced a real bug: a shoe-care brush classified as an apparel accessory and NOT gated (status=ready) — leaking into accessory search. Verify: 11 new unit tests green; root tsc --noEmit clean; sdk+server build (ESM+CJS+DTS) clean.

From ca302e5351abd8710a8d694a44165e6c59fcc9f3 Mon Sep 17 00:00:00 2001 From: octalpixel Date: Wed, 1 Jul 2026 13:47:24 +0530 Subject: [PATCH 02/14] feat(core): search eval on real corpus + Phase-1 NLQ fix (no "other" category) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reproducible search-relevance eval on the real fashionparity corpus (5,512 products), scored framework-direct via matcher.evaluateSearch (LLM-judge = gemini-3.1-flash-lite), with a pre-fix baseline and a post-fix run to compare. Eval: - examples/fashion-search/eval-search.ts — --phase=baseline|postfix; applies the config in-process (production path; NLQ schema/instructions are functions that can't come from the DB), groups the framework's per-query output into buckets, persists topIds, writes evals/runs/-search-. - evals/search-queries-typo.json — 12 misspelled queries added to the 50 golden queries. Data-driven finding: typo tolerance was NOT the gap (gemini-embedding-2 already handles typos — typo bucket 1.92 > 1.61 overall). The baseline exposed the real gap: use-case queries returned 30% NO RESULTS ("office wear for women", "smart casual outfit for men", "resort wear for a holiday"). Root cause + fix (packages/sdk/src/templates/fashion.ts): NLQ mapped vague queries to category:"other" — the non-apparel bucket — as a HARD filter, matching zero apparel. Removed "other" from the NLQ category enum and instructed null-for-vague; the model can no longer emit the poison value. Root fix, no engine coercion. Pre -> Post (k=5): use-case grade 1.23 -> 1.77 (+0.54), use-case no-results 30% -> 0%, overall no-results 5% -> 0%, overall grade 1.611 -> 1.679. Small style/local deltas (<=0.16) are within single-LLM-judge noise (unchanged hit counts) — not over-claimed; follow-up: persist a shared judge cache for deterministic pre/post. Also: annotated the stale gemini-3-flash-preview reference in BENCHMARKS.md — the live pipeline is gemini-embedding-2 + gemini-3.1-flash-lite (no flash 3). Verify: root tsc --noEmit clean; enrichment scorer tests still green (11/11).

Real BM25 = ParadeDB pg_search (mature, Tantivy) or VectorChord vchord_bm25 (early). BOTH need shared_preload_libraries → not on stock RDS/Aurora/Cloud SQL, and pg_search was DROPPED from new Neon projects (Mar 2026), both AGPL-3.0. => a deployment decision, not a code edit.

Grounded in 2024–2026 +sources (cited at the end); numbers are from vendor/community benchmarks, treat as order-of-magnitude. + +## TL;DR (the decisions) + +1. **samesake is nowhere near Postgres's scale limits and won't be for a long time.** Today ~5.5k + products; a *large* single fashion store is 10k–1M SKUs. PG's hard walls (HNSW index outgrowing + RAM) start around **10M × 1536-dim vectors (~80–120 GB index)** — 10–1000× beyond our "1". So the + scaling question is **not** sharding/billions; it's "right config for catalog-scale + know the exit." +2. **The only genuine near-term *quality* gap is #11 — the lexical leg (`ts_rank_cd`).** Every source + (even the pro-Postgres ones) agrees `ts_rank` ranking is weak (no IDF, no length normalization, no + TF saturation, no efficient top-N). Real BM25 exists in PG (**ParadeDB `pg_search`**, **VectorChord + `vchord_bm25`**) — but both need `shared_preload_libraries`, i.e. **a Postgres instance we + control**, and **`pg_search` was dropped from new Neon projects (Mar 2026)**. So #11 is a + *deployment* decision, which is exactly why it was deferred here rather than hot-fixed. +3. **Free wins available on ANY managed PG today (no infra change):** `halfvec` (2× smaller vectors, + ~2× faster build, <1% recall loss), **iterative index scans** (pgvector 0.8 — the built-in fix for + filtered vector search under-returning), **keyset pagination**, and **`setweight` field-weighting** + to make even `ts_rank` better.

Plus a **Tail Ranker** (sparse queries → lean on semantic relevance + generalized +cohort patterns) and **Overall Ranker** (new users → platform-level signals). + +## 2. Semantic search (the data-science deep-dive) — most on-point for us + +- **Framing:** retrieval as a **learning problem** — two-tower encoders in a shared space; decouples + retrieval from ranking; trained on weak supervision; optimizes semantic alignment not proxy metrics. +- **Training data = weak supervision from event logs** (Add-to-Cart, clicks) → positive query–product + pairs, cleaned (min-interaction thresholds, session dedup, near-duplicate query collapse). Treated as + "high-precision but incomplete," NOT ground truth. +- **Product representation = name + product_type + brand + LLM-extracted highlight attributes.** i.e. + **enrichment feeds the embedding** — "helps the model understand what a product actually is, not just + how it's titled." (Direct validation of samesake's `search_document`/enrichment-first thesis.) +- **Synthetic data for the tail (non-negotiable):** flag low-signal queries (≤5 interactions); retrieve + candidates with a strong external model → **LLM labels them highly/somewhat/irrelevant**; only + **highly-relevant used as training positives** (with in-batch negatives); **3-grade labels kept for + eval**. Also **generate synthetic queries from product descriptions** (vary specificity/phrasing). + Synthetic downweighted vs real events. +- **Loss = InfoNCE with in-batch negatives** (scales with batch size, auto-surfaces hard negatives). + Deferred triplet loss (unstable without a clean human gold set). +- **Model = all-MiniLM-L6** chosen for **latency/stability/robustness under noisy input**, not peak + offline accuracy. Custom bi-encoder **bootstrapped**: a large external model generated the first + signals → trained the production bi-encoder on them. +- **Staged training:** warm-up (all data, rising LR, avoids embedding collapse) → cascade (progressively + tighten ATC/click thresholds toward cleaner signal). +- **Evaluation (multi-pronged):** event-based forward eval (biased, for regression detection) + + **multi-model retrieval pooled + LLM-as-judge** + Precision@K model-as-judge. No single metric trusted. +- **Impact:** **up to 35% uplift** on impacted query segments; strongest on **tail / noisy / misspelled / + transliterated**.

Query correction (from flagship + linked post) +LLM-based (**Llama-3-8B**, self-hosted on Databricks, instruct-tuned), **grounded in the catalogue via +RAG** — embed the noisy query, retrieve top-K similar product/brand names, pass as context to prevent +hallucinating non-existent products. Handles phonetic Indian-vernacular typed in Latin script +("kothimbir"→coriander, "paal"→milk) where edit-distance correctors fail entirely.

Long-tail → route to nearest head query. +2. **Product representation for embeddings = title + product_type + brand + enriched attributes** — make + sure our embed doc composition includes the enriched attributes (we do; confirm it's the full set). +3. **Synthetic tail data + query generation** to bootstrap/strengthen the semantic leg and grow the eval + gold: LLM-grade candidates (highly/somewhat/irrelevant), train on top grade only, keep grades for eval; + generate queries from product descriptions. Cheap way to expand our 50-query gold set. +4. **Catalog-grounded LLM query correction** (RAG over product/brand names) for multilingual/phonetic — + the concrete answer to our deferred multilingual gap. +5. **Explore stream** alongside exploit to counter rich-get-richer for new/low-engagement SKUs (we only + exploit). +6. **Ops rules layer** (boost/deboost/bury by query, no deploy) — our L3 merchandising gap. + +**Differs / do NOT copy (quick-commerce specifics that are over-engineering at our scale):** +- **Hyperlocal city-pvid index with nested per-store metadata + eligible-hub filtering** — Zepto's + inventory changes per-second per-hub; a fashion catalog per store is far stabler. We don't need this. +- **"Full-page caching is impossible"** — true for them (inventory×cohort×experiment cardinality); for a + fashion store, result caching is more viable. +- **MoE cohort-gated ranking, Tail/Overall rankers, 1M req/min infra** — warranted at their scale/traffic; + premature for us. Our BYO cross-encoder + boosts is right for now. +- **Product Assortment Service as a separate ground-truth resolver** — their index/inventory lag is + seconds; for us, price/availability freshness is a lighter concern. + +**Net:** Zepto independently confirms the samesake spine — hybrid retrieval, enrichment-feeds-embeddings, +compact custom encoder, LLM-judge eval, retrieval-quality-sets-the-ceiling. The transferable ideas are +**head/tail query-understanding tiers, synthetic tail data, and catalog-grounded LLM correction**; the +divergences (hyperlocal per-hub inventory, MoE, no-caching) are quick-commerce-specific and would be +premature scaling for a fashion catalog. + +## Sources +blog.zepto.com/building-search-for-a-10-minute-world · /how-we-built-high-precision-low-latency-semantic-search-in-production +· /from-bottleneck-to-breakthrough-how-we-rebuilt-product-enrichment-at-scale · (linked) +blog.zeptonow.com/lost-in-translation-...(query correction) · /personalized-search-ranking-the-zepto-way (ranking).

Grounds the L3 "toolkit" layer from `docs/architecture/full-scale-fashion-search.md`. + +## 1. Motivation + +samesake has a strong retrieval core and three consumption surfaces (in-process, `fetch`, Hono), but a +frontend developer wiring intent search into a React storefront today writes all the plumbing by hand: +debounced as-you-type, request abort/dedup, facet-refinement state, URL sync, SSR hydration, and — the +part nobody else has — surfacing samesake's **NLQ transparency, intent/similar modes, image search, +spaces weights, and `/explain`**. Algolia ships InstantSearch for exactly this DX; the OSS engines +(Typesense/Meilisearch) ship InstantSearch *adapters*. We have nothing. This is the biggest adoption +lever and the L3 gap flagged in the architecture doc and the industry research. + +**The "1":** the fastest way to put samesake's *intent-driven fashion search* into a React app — a +typed, transport-agnostic client + **headless** hooks that expose our differentiators — with +InstantSearch-grade DX but without InstantSearch's widget/CSS bloat. + +## 2. Prior art — steal / avoid + +**Algolia InstantSearch / React InstantSearch** +- STEAL: the **connectors/headless** split (logic hooks decoupled from UI) — `useSearchBox`, `useHits`, + `useRefinementList`, `useInfiniteHits`, `usePagination`, `useCurrentRefinements`, `useStats`; a single + **search-state manager** that batches all widget state into **one request per keystroke**; **URL + routing/sync** of search state; SSR support. +- AVOID: the widget "batteries" + bundled CSS, the heavy `` ceremony, federated + multi-index complexity, and a proprietary query DSL. The modern React norm (shadcn era) is + headless-first: give devs the state + a11y, let them bring markup. + +**`autocomplete-js`** — STEAL the sources/state/plugins model + keyboard a11y for the as-you-type +dropdown; but it's imperative/vanilla — we want React hooks. + +**Typesense / Meilisearch InstantSearch adapters** — STEAL the "adapter maps our API to a stable client +protocol" idea, but as **optional interop later**, not the core. Our differentiators (modes, NLQ chips, +spaces weights, `/explain`, image) do not fit the InstantSearch protocol, so a native client is the +core; an IS adapter is a bridge for teams already invested in InstantSearch. + +**TanStack Query / Router** — STEAL the async/caching/dedup + URL-state discipline. Decision: **do not +hard-depend** on TanStack (keep the core zero-dep) but design hooks so a TanStack Query integration is a +trivial recipe. + +## 3. The real API we wrap (grounding — verified against `packages/server`) + +Request (`SearchOpts` / `POST …/search`): `{ q, image{url|bytesBase64|mimeType}, filters (Mongo-style), +weights (Record>), mode:"intent"|"similar", rerank?, diversify?, +limit?, offset?, facets? }`. +Response (`SearchResult`): `{ hits:[{id,score,data,...}], parsed?, constraintTrace, nlq_degraded?, +relaxed, took_ms, facets?:Record, total_candidates?, cached? }`. +Also: `POST …/facets {filters,facets}` (query-free) → `Record`; **`POST +…/collections/:collection/search/explain`** → `ExplainDocBreakdown {id, fts_rank, cosine_rank, +spaces_rank, recency_rank, rrf_score, space_cosines}` (in-process `matcher.searchExplain`); in-process +`matcher.search/facets`; agent tools `findProducts/findSimilarProducts`. Every client method maps 1:1 +to one of these — all verified to exist in `packages/server`. + +The client is a **thin, exact, typed** wrapper over this — no fictional fields. + +## 4. Architecture — three layers, transport-agnostic + +``` +@samesake/react (L3) hooks + + optional headless components [peer: react] + │ binds +@samesake/client/headless (L2) framework-agnostic search-state controller + │ (debounce · abort · dedupe · merge refinements · URL codec · subscribe/getState) +@samesake/client (L1) typed transport-agnostic client [zero deps] + │ createClient({ baseUrl,apiKey } | { matcher }) → search/facets/explain + ▼ + HTTP fetch ──or── in-process matcher (same interface; SSR/edge uses in-process) +``` + +Two published packages: **`@samesake/client`** (L1 core + L2 headless as `@samesake/client/headless`, +zero runtime deps) and **`@samesake/react`** (L3, `react` as a peer dep). Rationale: keep the core +usable in any framework / server / worker; only the React bindings pull React. + +### L1 — core typed client (`@samesake/client`) + +```ts +export interface SearchClient { + search(project: string, collection: string, params: SearchParams, opts?: CallOpts): Promise; + facets(project: string, collection: string, params: FacetParams, opts?: CallOpts): Promise; + explain(project: string, collection: string, id: string, params: SearchParams, opts?: CallOpts): Promise; +} +export interface CallOpts { signal?: AbortSignal } // abort stale requests + +// HTTP transport (browser/edge) OR in-process (SSR) — same shape: +export function createClient(cfg: + | { baseUrl: string; apiKey?: string; fetch?: typeof fetch } + | { matcher: MatcherLike } // reuse the running matcher on the server +): SearchClient; +``` + +`SearchParams`/`SearchResult`/`FacetResult` are **re-exported from `@samesake/core`** so client and +server share one source of truth (no drift). The HTTP transport builds the `POST …/search` body; the +in-process transport calls `matcher.search`. Errors normalize to a typed `SamesakeError`. + +### L2 — headless search-state controller (`@samesake/client/headless`) + +A tiny store (subscribe/getState/dispatch) that owns the full search UI state and turns interactions +into **one batched request**: + +```ts +export interface SearchState { + query: string; mode?: "intent" | "similar"; image?: ImageInput | null; + refinements: Record; // facet selections → filters + weights?: WeightsInput; // spaces/channel weights + page: number; hitsPerPage: number; + status: "idle" | "loading" | "stalled" | "error"; + results?: SearchResult; error?: SamesakeError; +} +export function createController(client: SearchClient, cfg: { + project: string; collection: string; + debounceMs?: number; // default 150 + facets?: FacetParams; // request facet counts alongside hits (one round-trip) + initialState?: Partial; + router?: UrlRouter; // optional URL <-> state sync +}): SearchController; + +export interface SearchController { + getState(): SearchState; subscribe(fn: () => void): () => void; + setQuery(q: string): void; setMode(m?: Mode): void; setImage(i: ImageInput | null): void; + toggleRefinement(field: string, value: unknown): void; clearRefinement(field: string): void; + setWeights(w: WeightsInput): void; setPage(n: number): void; + removeConstraint(c: ConstraintRef): void; // remove an NLQ-parsed hard filter (see §5) +} +``` + +Guarantees (the DX Algolia gets right): **debounce** keystrokes, **abort** the in-flight request when a +newer one starts, **dedupe** identical requests, mark `stalled` if a response is slow, and **merge** +query + refinements + weights + page into a single `client.search` call. `UrlRouter` is a pure +codec (`stateToQuery`/`queryToState`) so state is shareable/back-buttonable; framework routers plug in. + +### L3 — React bindings (`@samesake/react`) + +`` creates the +controller and provides it via context; `useSyncExternalStore` subscribes (SSR/concurrent-safe). Hooks +are **headless** (return state + handlers, no markup): + +```ts +useSearchBox() → { query, setQuery, clear, isSearching } +useHits() → { hits: Hit[], results, status } +useInfiniteHits()→ { hits, loadMore, hasMore, isLoadingMore } +usePagination() → { page, nbPages, setPage, next, prev } +useStats() → { nbHits: total_candidates, tookMs, cached } +useFacet(field) → { items:{value,count,refined}[], toggle(value), clear } // enriched facets +useCurrentRefinements() → { items, remove(ref), clearAll } +useMode() → { mode, setMode, autoSimilar } // intent/similar +useImageSearch() → { setImage, image, clear } // screenshot / "more like this" +useConstraintChips()→ { chips:{field,label,value}[], removeChip, relaxed, nlqDegraded } // NLQ transparency +useWeights() → { weights, setWeight(path,val), reset } // spaces sliders (dev/merch) +useExplain(id) → { breakdown, isLoading } // /explain dev overlay +``` + +Optional **unstyled headless components** (thin wrappers, bring-your-own-markup, shadcn-friendly): +` +`. **No bundled CSS. No widget zoo.** (This is the deliberate anti-InstantSearch choice.) + +## 5. The samesake differentiators the SDK surfaces (why this isn't an Algolia clone) + +1. **intent / similar modes** — `useMode()`; auto-`similar` when an image is set; ``. +2. **NLQ transparency (unique)** — `useConstraintChips()` reads `parsed` + `constraintTrace` and renders + what the engine *understood* as removable chips ("under ₹5000", "red", "for a wedding"); `removeChip` + re-issues the search without that hard filter. Surfaces `relaxed`/`nlq_degraded` as a notice ("showing + close matches — relaxed 'sleeveless'"). No other search SDK has this because no other engine turns NL + into inspectable hard filters. This is the headline DX. +3. **image / "find similar"** — `useImageSearch()` (upload/screenshot) + a "more like this" affordance on + a hit (search by that product's image, mode=similar). +4. **spaces weight tuning** — `useWeights()` exposes query-time visual/price/freshness/channel weights + (the "tune without reindex" capability) — a merchandiser/dev slider panel. +5. **enriched facets** — `useFacet('color'|'occasion'|'style'|…)` over enriched attributes; soft facets + (relaxable) vs hard, reflected in chip behavior. +6. **`/explain` overlay** — `useExplain(id)` shows per-leg ranks + space cosines; a dev-mode relevance + debugger baked into the SDK. +7. **variant diversification / buy-again** — passed through on hits for the UI to badge. + +## 6. DX essentials (table stakes, from Algolia + OSS) + +As-you-type with 150ms debounce · abort stale + dedupe identical · optimistic query echo · URL state +sync (opt-in) · keyboard-a11y search box · infinite scroll + numbered pagination · SSR initial results + +hydrate · explicit loading/empty/error/stalled states · TypeScript-first (generic `Hit` typed to the +collection's field shape) · tiny bundle (core zero-dep; react peer-dep). + +## 7. SSR / RSC + +Core client runs **in-process** on the server (`createClient({ matcher })`) for React Server Components / +edge, so the first result page renders server-side with zero client JS; `` hydrates the controller so the first client interaction has no refetch. Next.js App +Router: a server component fetches initial results (in-process or HTTP) and passes them to a client +``. Works on Cloudflare Workers (the matcher already runs there via Hyperdrive→PG). + +## 8. Packaging & deps + +- `@samesake/client` — L1 + L2 (`/headless` subpath). **Zero runtime deps.** Types from `@samesake/core`. +- `@samesake/react` — L3. Peer deps: `react` (18/19), `@samesake/client`. +- Build: `tsup` (ESM+CJS+DTS), matching the other packages. No `.map` files in the tarball. Tree-shakeable. + +## 9. Phased build plan (lean increments) + +- **P1 — L1 core client** (HTTP + in-process transports, typed to core, abort/error).

Verify in a real Next/Vite app. +- **P4 — headless components + docs + example** (wire the `examples/fashion-search` storefront UI; + a docs guide `apps/docs/.../guides/react-search.mdx`). +- **P5 — optional, deferred:** an autocomplete/`useSuggest` hook (needs a `/suggest` endpoint — ties to + the L3 toolkit autocomplete gap) and an `@samesake/instantsearch-adapter` interop bridge. + +## 10.
