How to repair all indexes in a MySQL database?
Perhaps you should look for all tables that have fulltext indexes

SELECT DISTINCT table_schema,table_name
FROM information_schema.statistics
WHERE index_type='FULLTEXT';


To individually remake all tables that have FULLTEXT indexes

REPAIR_SQL_SCRIPT=RemakeTables.sql
SQL="SELECT"
SQL="${SQL} CONCAT('ALTER TABLE ',db,'.',tb,' ENGINE=',eng,';')"
SQL="${SQL} FROM (SELECT A.table_schema db,A.table_name tb,B.engine eng"
SQL="${SQL} FROM (SELECT DISTINCT table_schema,table_name"
SQL="${SQL} FROM information_schema.statistics WHERE index_type='FULLTEXT') A"
SQL="${SQL} INNER JOIN information_schema.tables B"
SQL="${SQL} USING (table_schema,table_name)) AA"
mysql -uroot -ANe"${SQL}" &gt; ${REPAIR_SQL_SCRIPT} 
cat ${REPAIR_SQL_SCRIPT}


If you are OK with the contents of RemakeTables.sql, then execute it:

mysql -uroot &lt; ${REPAIR_SQL_SCRIPT}


CAVEAT : All indexes are remade as well
