I got pretty simple question, but i can'f find and answer rly. After i index document in ES it wil be commited to index in about 1 second. What will happen to my cache filled with filter query ealier. It will be cleared to give me most current response? In solr when i index and commit new document new searcher is boarn and all cachech are cleared.

Hi Marcin, Elasticsearch caches filters per segment. Let's say that you have a search S and a filter F which is cached. If you perform updates, then a new searcher S2 will be created, that likely shares most of its segments with S. So on the next time that you will be using F in a query, Elasticsearch will only generate cache entries for the segments of S2 that were not part of S.
