Hi, I was wondering if anyone was able to help me out with a small question regarding the advanced search functionality.

I am aware that (in PHP) the search variables for a standard search can be fetched with $_GET['_search'], $_GET['searchOper']…(etc)..however I cant for the life of me work out how to fetch the multiple criteria/terms passed with an advanced search. Is the data serialised and/or passed in an array (i.e. searchOper[0, 1, 2, etc…]). Also, as an aside, the '_search' variable always appears to be 'true', regardless of whether a search is being made or not, not sure if this is a bug/issue?

Many thanks for any help, much appreciated!
