If you want to convert MYSQL tables to INNODB use the following script:
mysql -u root -p -e "SHOW TABLES IN DATABASE-NAME;" | tail -n +2 | xargs -I '{}' echo "ALTER TABLE {} ENGINE=INNODB;" > alter_table.sql
and then run:
perl -p -i -e 's/(search_[a-z_]+ ENGINE=)INNODB/\1MYISAM/g' alter_table.sql
Replace “DATABASE-NAME” with your database name. You also need root access (preferably).
