Search query location
I am attempting to edit the search, but I can not seem to find the location of a couple things.
<input type="text" name="location" id="search-location" class="text" value="<?php va_show_search_query_var( 'location' ); ?>" />
Where is this function located in the files va_show_search_query_var?
Also, where are the global variables such as location located?
