Comment 2 for bug 1534979

If what Dan suggests doesn't get you what you want, I think it would be more fruitful to look into using depth (that is, the depth=0 CGI paramter) rather than adding yet another layer of complexity and obfuscation to the already confusing "where am I actually searching" logic. The depth parameter does (and was always intended to do) exactly what you want -- focus on a particular location, but search everywhere.
