that shouldn't be too difficult, by I do have a few things that are more pressing at the moment.
what's the use of it? compared to say, letting sickrage search directly?
So it's actually neat idea. You plug in all your indexers and it can do a couple things:
1) use nzbhydra as your search engine - it will search all your indexers and give you a consolidated list of results across all indexers. it's smart enough to know the categories and can send to sabnzbd or nzbget appropriately
2) (and why i love it) use nzbhydra as a proxy for your sickrage/couchpotato/etc. In those apps, the only indexer is nzbhydra, and it proxies all requests for you. so the next time you find a new indexer, you just add it to nzbhydra and it's now provided for all your apps.
it also lets you set api limits for indexers so you're not banging away at ones that aren't returning results
it also tracks statistics, so you can see which indexers are doing the best job and worth your $ ;D
