-- FAQ --

Q: Why should I use this module?

A: The search index can become massive on large sites, making it difficult to transfer the site to another server.
Examples include migrating ISPs or just creating a test site. Yes, we know it would be better to not delete the
entire search index, but its sheer size sometimes forces the need.

Q: I wiped my search index, How do I rebuilt it?

A: It is similar to Rebuild index button, we need to run cron on the site to rebuilt the index.
