Which search index should be used with php and postgresql clustered

Question

When writing a PHP application which search index should be used if you want to index a lot of documents in a clustered fashion. Is there a simple library to do the job? Is there something like lucene for php?

Answer 1

About Lucene and PHP, there is Zend_Search_Lucene, which is part of the Zend Framework (Which means well tested, well supported, well programmed, quite well documented... But might also means some work if you want to use it without the rest of the framework...).

Note that, quoting the doc :

Zend_Search_Lucene is a general purpose text search engine written entirely in PHP 5. Since it stores its index on the filesystem and does not require a database server, it can add search capabilities to almost any PHP-driven website.

Which means you don't depend on anything else than PHP -- which may be nice too.
