Question

I am a bit new to MySQL Full Text Search capability.

I would like to clarify some usage of MATCH()..AGAINST() FTS functionality.

If we have a column of type text and which contains multiple name pair values along with other text. Generally I understand that the FTS feature in MySQL can be used as via below command:

select col from mytable where match(text_data) against('some word') limit 10;

But I need to search for multiple words like, if:

select text_data from mytable;
==============================

abcd, xyax&iopp data=1244 amt=78 ..
abcd, xyax&iopp data=12xx amt=7x ..

Now I want to search in text_data column having value data value as ‘1244’ and amt as ’78’. So how can I use two expression is AGAINST clause:

select col from mytable where match(text_data) against ('data=1244' and  'amt=78')

OR

select col from mytable where match(text_data) against ('data=1244') and match(text_data) against ('amt=78')

OR

select col from mytable where match(text_data) against ('data 1244 amt 78') 

OR

is there any other way?

Answer 1

SELECT  col
FROM    mytable
WHERE   MATCH(text_data) AGAINST('+"data 1244" +"amt 78"' IN BOOLEAN MODE)

Note that you should have ft_min_word_len set to 1 for this to work (with default value of 4, amt and 78 won’t even get indexed)
