Why Does My MATCH AGAINST Query Fail with \'Can\'t find FULLTEXT index matching the column list?\'

MATCH AGAINST Query Fails with FULLTEXT Index Error

Q: While working with fulltext indexing, an error occurs when attempting to search for a value using MATCH AGAINST:

"Can't find FULLTEXT index matching the column list."

A: This error typically indicates that the fulltext index specified in the MATCH AGAINST clause does not align with the column list in the table. To resolve the issue, follow these steps:

• Confirm that you have created a fulltext index that includes the brand column. If not, execute the following command to add it:

ALTER TABLE products ADD FULLTEXT(brand);

• Ensure that the number of columns and their order in the fulltext index match exactly those in the MATCH clause. In this case, the fulltext index is correct since it includes the brand column and is ordered as expected.
• Additionally, check if the uniqueness or primary key constraints are defined on any of the columns included in the fulltext index. These constraints can prevent the creation or usage of the fulltext index. If they exist, try removing them or modifying them to not conflict with the fulltext index.
