I have an article table with 2 columns
Id INT(4) PK autoincrement Description VARCHAR(250) (and more columns)
This table contains 500.000 records and is a INNODB table.
Now I want to search an article like this:
SELECT COUNT(*) FROM article (description like '%cannon%');
It takes almost a second to execute ..
What can I to to make this faster?
I have alread an index on the Description column
Queries with
like '%cannon%'are very hard to optimize. No, indexes can’t help you. Maybe full-text search can help you.
