First of all thanks for the great work you did on this. Especially the different user (.htpasswd) function made my life a lot easier.
There's only one thing; I seem to have some problems with the search function in the PHP version. If I conduct a search all is well, if I conduct a second search, without logging out and in again, it only searches within the first search results. Is there a way, like in the original (kovidgoyal) version, to search from scratch?
