vdi ud diy: improve site search functionality

[danicahelb]

Site search: add additional fields to the "Study" document

see redmine: https://redmine.apidb.org/issues/49792?jump=my_page

"Study" document is confusing to users as it currently only searches things on the study page:

• Associated publications
• Data access records
• Description
• Study Name
• Principal Investigator and Collaborators
• Study Characteristics
• Summary

Users expect that "Study" will return ANY study where the term hits ANY of the fields. Please add additional fields to the "Study" document, including all fields in the Variables and Variable values:

• Category
• Study specific variable information table
• Variable name
• Variable value

Info from @iodice

Category is not included yet.

Study specific variable information table, Variable name, and Variable Value are included, as “Study Characteristics”, “Attribute names” and “Attribute values”.

This ticket should be QA'd now but remain open until Category is included

“Study Characteristics” represents Study specific variable information table, verbiage may be ok?

“Attribute names” represents variable names --> this verbiage needs to be updated

“Attribute values” represents values --> this verbiage needs to be updated

please implement on the new VDI DIY site and also the legacy sites
