A simple Mini Search Engine built in C++, which indexes text files and allows you to search for words across multiple files — showing which files contain the word and how many times it appears.
✅ Reads multiple text files from a folder
✅ Builds a searchable index of all words
✅ Case-insensitive search
✅ Displays how many times a word appears in each file
✅ Beginner-friendly, uses only C++ STL
✅ Extendable to more advanced versions (ranking, multi-word search, etc.)
Building search index... Index built successfully! ✅ Total unique words indexed: 7
