It's done in the advanced search function, but it seems you cant just add this to a page.
So I want to do a "contains any of the words in the string" search.
Is there a way to this?

Just found this...
SELECT id, article FROM mytable WHERE MATCH(article) AGAINST ('+word1 +word2' IN BOOLEAN MODE)
does return result, but is very slow.
At the same time, another query
SELECT id, article FROM mytable WHERE MATCH(article) AGAINST ('+word1' IN BOOLEAN MODE) AND MATCH(article) AGAINST ('+word2' IN BOOLEAN MODE)
returns the same result, but could be 100 times faster...
So I'm looking at passing a string slicing it up and building the query.
What do you think?

OK, I've got it working. So the users adds "tags" to a search box and they're passed, sliced and rebuilt into the sql with each of the words an OR option.
Any Ideas how I can make the records that have more of the keywords appear closer to the top of the results?
:)

Big table i will do nothing.
Small Table i will create a Temporary Relevance Counter.
How big are your table?
MySQL or MSSQL?

INNDODB or MyISAM?
