Why Does \'Can\'t find FULLTEXT index matching the column list\' Error Occur and How to Fix It?

Unable to Identify FULLTEXT Index for Specified Column List

While implementing a fulltext search on a table, you may encounter the error "Can't find FULLTEXT index matching the column list" despite successfully adding the index.

Root Cause:

This error occurs when the fulltext index created does not match the columns specified in the MATCH clause.

Solution:

To resolve this issue, ensure that the fulltext index contains the exact same number of columns in the same order as mentioned in the MATCH clause.

Specific Example:

In the provided scenario, the fulltext index is defined for the following columns:

FULLTEXT KEY `name` (`name`,`breadcrumb`,`description`,`brand`,`price`,`year`,`km`,`usage`,`type`)

However, the MATCH clause in your query only includes the brand column:

SELECT * FROM products WHERE MATCH(`brand`) AGAINST('Skoda');

To resolve this discrepancy and enable successful fulltext searching, execute the following query:

ALTER TABLE products ADD FULLTEXT(brand);

This will create a separate fulltext index for the brand column, ensuring it matches the specified column list in your MATCH clause.
