[Xapian-discuss] Using boolean terms in PHP bindings

[Ryan Mahoney]

OK, I figured out how to implement this properly, have to say, it wasn't 
so intuitive!  Maybe after this project I will try to work on some extra 
tutorials for the PHP bindings.  Here's the code correction:

    //set prefix
    queryparser_add_boolean_prefix($query_parser, "category", "XC");

    //parse and create the query
    $query = queryparser_parse_query ($query_parser, $_REQUEST["search"] 
. " category:22");
