Yeah, i would say insanely fast indexing speed is a winner at 3 stages of a) developing the 2 or 3 indexes you need for good search results b) running test suites c) production That said, in the past, I haven't been able to transfer the index configuration from sphinx to SOLR indexes and get 98% matches between the 2 engines. Sphinx (thinking sphinx in rails) used to do funny stuff in the pre-1.0, like if you put in 2 search terms you would get X results, if you put in those 2 terms plus another, you would get more results. I think they've fixed most of that in 1.0
