How to Improve Searchability in Knowledge Base

[lynchmk]

Can someone tell me which primary field improves searchability in the Knowledge Base more than any other(s)?  For example, say I have a Knowledge Article #1 where "XYZ" appears in the Title of the article, the Meta field, and in the body of the article.  Well, say I also have a Knowledge Article #2 where "XYZ" appears once in the body of the article ONLY.  ("XYZ" does NOT appear in the Title or in the Meta field.)

When I do a search of "XYZ" in the Knowledge Search, Article #2 appears above Article #1 in the search results.  How can this be?  Why does Article #1 (which has XYZ in the Title field, Meta field, and body of the article) not appear at the top of the search results list?  

Can someone please assist?  Thank you!!

I'm not sure I can assist you as I face also difficulties in improving knowledge search.

What I undestood from documentation is that you can give a search weight to these fields of kb_knowledge table by adding an attribute to the fields in system table properties. You can look there in this doc entry : link

For my part I'm in difficulty with attachment weight. Article with one or more attachement that contains the search terms are always coming at the top of the search. Even if I put more weight on description and meta fields...
