So PostgreSQL fulltext search and sphinx search have already been integrated. Sphinx error reporting has been improved with proper logging and error display in case search fails. I am working on improving postgresql fulltext search as it mis-behaves on -foo treating it like foo. Access specifiers will be added and ACP UI code which is currently passed on as a variable will be moved to a new HTML file like: adm/style/search_fulltext_sphinx.html
Intend to write some tests too. Is there anything else I am missing out on, that can be improved/ introduced in phpBB search backends?
