I've been creating a new add-on which implements some advanced search functionality to bolt onto Enhanced Search. MySQL-based search is not supported, nor planned, and this add-on only works with Enhanced Search. This add-on injects per-content type weighting for general searches with more than one content type. Then sorting by relevancy is enabled; the weighting is multiplied by the arbitrary score Elastic Search computes for each item. The new per-content type weighting options are under 'Search Options'. Please do not deploy this to a Live site, as it is still under development and I haven't tested it extensively! I have a alpha copy of my Search Improvements add-on with this functionality now here. I need to experiment with the exacts of how the weighting is applied as it really isn't easy to determine what is a sane value to weight each content-type. I'ld love some feedback on this add-on so far. But please don't deploy it to your live site yet! I've implemented a query-time priority, but I'm not happy about the implementation due to the lack of flexibility with the XenForo Elastic Search API bits.
