Thread:Extension talk:SphinxSearch/SphinxSearch and MediaWiki 1.19.0 -- fixed/reply

Perhaps page_is_redirect is missing in the sphinx.conf? It did not use to be there by default, but in more recent versions you should see it in at least three places in your sphinx.conf, in both sql_query settings, and in one sql_attr_uint setting. After you change the config file, you need to reindex the wiki.
