Hi, Thought you guys might be interested, I'm working on a search abstraction library for PHP called Forage, you can check it out at the link below. At the moment it just supports basic indexing and searching with Xapian, Solr and Zend Search Lucene but I'm hoping to add more engines and more features (tagging, faceting, etc) in the very near future. By the way, I haven't forgoten about implementing iterators for the PHP5 bindings, I've just not had a chance to look at SWIG. I've put some time aside this weekend for taking a look. Cheers Rob http://code.google.com/p/forage
