[SOLVED] Full-Text Score without Dependency
Posted by: Peter Schmidt

Hi,

I can't find the solution for the following problem: I need to order a result by the full-text score but I don't want to make this match an exclusion for other rows that have actually no match in this column. Unfortunately I get a result/full-text score only if I use the MATCH () AGAINST in the WHERE-Condition.

What I'd need to have:
SELECT *, MATCH (FULL_TEXT_COLUMN) AGAINST ('full text words') as FULL_TEXT_RELEVANCY FROM my_table
WHERE OTHER_COLUMN = 'value'
ORDER BY FULL_TEXT_RELEVANCY

What's kind of working (but excludes rows without full text match):
SELECT *, MATCH (FULL_TEXT_COLUMN) AGAINST ('full text words') as FULL_TEXT_RELEVANCY FROM my_table
WHERE OTHER_COLUMN = 'value'
AND MATCH (FULL_TEXT_COLUMN) AGAINST ('full text words')
ORDER BY FULL_TEXT_RELEVANCY

Also not working as intended (FULL_TEXT_RELEVANCY is always 0) :
SELECT *, MATCH (FULL_TEXT_COLUMN) AGAINST ('full text words') as FULL_TEXT_RELEVANCY FROM my_table
WHERE OTHER_COLUMN = 'value'
OR MATCH (FULL_TEXT_COLUMN) AGAINST ('full text words')
ORDER BY FULL_TEXT_RELEVANCY

Thank you for any possible help!
