One of your .map files probably references a symbol that is not in

This is QueryByPoint with a similar error,
http://www.mapserver.org/errors.html#msquerybypoint-search-returned-no-results.
 Not sure if it is applicable to QueryByRect.

There may be some hints for the "Cannot evaluate expression, no item
index defined." message in this thread,

You may also want to up the level of debug output to 5 to get more
detail, and look at the actual query sent to the datasource.
Sometimes seeing what is actually sent shows something obviously
incorrect and then you can focus on why that parameter is incorrect.
