Thread:Talk:MediaWiki/Search Bar no longer working

My search box suddenly stopped working. This is extremely inconvenient. I did not create the wiki myself, it was inherited, and I am not sure how to go about fixing this issue. Please Help, anything you can suggest!?!

Here is the error I get:

A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:

(SQL query hidden)

from within function "SearchMySQL::searchInternal". Database returned error "145: Table './callcenter/searchindex' is marked as crashed and should be repaired (localhost)".
