Hi,

I would second erix' suggestion to work with posgresql for its full text search capabilities; see https://www.postgresql.org/docs/13/textsearch.html

You can do a lot of things with tsvector, see for instance https://www.postgresql.org/docs/13/textsearch-features.html#TEXTSEARCH-MANIPULATE-TSQUERY

Very powerful, not so hard to use. Your timeframe to understand the documentation and implement something is a bit short, though, from what I read in another post of yours.
