MySQL Error 1191: Missing FULLTEXT Index
Description
This error indicates that MySQL cannot locate a FULLTEXT index that covers all the columns specified in your MATCH AGAINST query. It commonly occurs when a FULLTEXT search is attempted on columns that do not have such an index, or the existing index doesn't include all the relevant columns.
Error Message
Can't find FULLTEXT index matching the column list
Known Causes
4 known causesNo FULLTEXT Index Defined
The table columns you are attempting to search using MATCH AGAINST do not have a FULLTEXT index defined on them at all.
Incomplete FULLTEXT Index
A FULLTEXT index exists, but it does not include all the columns specified in your MATCH AGAINST clause, leading to a mismatch.
Unsupported Storage Engine
FULLTEXT indexes are primarily supported by MyISAM and InnoDB (from MySQL 5.6+). If the table uses an unsupported engine, the index cannot be created or used.
Query Column Mismatch
The columns listed in the MATCH part of your MATCH AGAINST query do not correspond exactly to the columns defined in any existing FULLTEXT index.
