It's not possible to use

MATCH(column) AGAINST('keyword')

syntax for columns with no FULLTEXT index. Let's run the following query on column

first_name

that has not FULLTEXT index:

SELECT * 
FROM students 
WHERE MATCH(last_name) AGAINST('გიორგი')

Then we will get the error:

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

Note:

MATCH(column) AGAINST('keyword')

syntax can only be used on columns with FULLTEXT index
