Thread:Extension talk:SphinxSearch/search in command line ok - in browser no results

Hello, I am using sphinx-0.9.9-6.4, SphinxSearch 0.8.5, MediaWiki 1.19.1, Linux Suse 11. I followed the install and setting guide. Searching in command line works just fine. Searching in browser displays: There were no results matching the query. Any idea is welcome. Thanks, Adam
