Question

I’m trying to run a simple query like this:

SELECT *, 
MATCH(`col1`,`col2`) 
AGAINST ('some text') AS score
FROM `mytable` ORDER BY score DESC

This always gives the error:

#1191 - Can't find FULLTEXT index matching the column list

But if I split the columns and do two queries like this:

SELECT *, 
MATCH(`col1`) 
AGAINST ('some text') AS score
FROM `mytable` ORDER BY score DESC

and:

SELECT *, 
MATCH(`col2`) 
AGAINST ('some text') AS score
FROM `mytable` ORDER BY score DESC

Then that works. Why can’t I match against both columns at the same time? I see an example on the manual doing almost exactly the same thing like this:

mysql> SELECT id, body, MATCH (title,body) AGAINST
    -> ('Security implications of running MySQL as root') AS score
    -> FROM articles WHERE MATCH (title,body) AGAINST
    -> ('Security implications of running MySQL as root');

Answer 1

#1191 - Can't find FULLTEXT index matching the column list

You need to have FULLTEXT index on both the columns together.
FULLTEXT (col1,col2)
