I am going to be working with a medium index of 200k to 1m documents. Occasionaly, there will be single document corrections applied to this index. I am worried about this action clearing my sort buffers. I saw the method of priming another searcher, but if you have a bunch of fields that may be sorted that could take longer than I want (I am trying to get as close to realtime as possible). Would it make any sense in trying to save the sort cache, insert the new doc in that (whatever that entails, I don't know), and then pass the sort cache to a new searcher? Or something along those lines...?
Does that sound completely crazy or do you have a much better way for me to try? Or mabye I am worrying about nothing at all... Thanks for comment, Mark
