USAGE: $0 [ --change-driver=DRIVER --reindex ]
This utility will either rebuild a search index, or allow you to switch
between different search drivers.
The following drivers are currently available:
$drivers
To switch to a new driver, pass in the driver you want to use like:
$0 --change-driver=MYSQL
To rebuild the search index, call:
$0 --reindex
