Thread:Extension talk:SphinxSearch/search is sometimes case sensitive/reply

I just tried on your site and both "adopting a feral dog" and "Adopting a Feral Dog" bring back the same search results. The only difference in when you press enter instead of clicking Fetch. In that case the lowercased search still brings back the usual results, but the correctly cased search will redirect you to the actual article, because that is an exact match.
