Thread:Extension talk:Zend Search Lucene for MediaWiki/Search in Microsoft Office documents ( doc, docx, xls, xlsx etc. ) and pdf./reply

There is currently no timeline to implement new features mentioned as todo's on the extension main page, as long I don't receive urgent, further comercial development assignments. I will do this for sure, but please consider every single kind of file-extension needs a serious programming job in search engine land. Reindexing is needed by every search engine. You can do this incremental or full. The implementation of this could vary. As mentioned a common way to do this is triggering the indexer script by a cronjob. But theoretically this could be happen after every editing action (may be a little bit crazy).

UPDATE: All this features are realized with the next upcoming release (see main page announcements).
