then inversely, we could match table lamps, but not table?

query_by does prefix search on keywords by default. So ele will match elephant etc. Also table will match table lamps also because we will pull up all documents that contain the word table.

Would setting prefix off for that field help the issue?

What is the exact issue? Give me exact query used and the documents that did not match but you expected to.

additionalSearchParameters: {      
query_by: "product_cat, pa_material, pa_color, pa_collection, pa_theme, pa_style, post_title", 
sort_by: "_text_match:desc"
},

I think the term is phrase matching?

I would want product_cat to see that “table lamps” does not match “table”

Try with "table lamps" (wrap query in quotes)
