Suppose I have two columns, keywords and content. I have a fulltext index across both. I want a row with foo in the keywords to have more relevance than a row with foo in th

Answer 1

As far as I know, this isn't supported with MySQL fulltext search, but you can achieve the effect by somehow repeating that word several times in the keyword field. Instead of having keywords "foo bar", have "foo bar foo bar foo bar", that way both foo and bar are equally important within the keywords column, and since they appear several times they become more relevant to mysql.

We use this on our site and it works.
