Hi Kaya, The answer is simple: as much as your requirements allow delay between data being indexed and changes being visible. It is sometimes seconds and sometimes hours or even a day is tolerable. On each commit your caches are invalidated and warmed (if it is configured like that) so in order to get better use of caches, you should commit as rare as possible.
The setting that you provided is about hard commits and those are configured not to open new searcher so such commit does not cause “exceeded limit” error. You either have soft auto commits configured or you do explicit commits when updating documents. Check and tune those and if you do explicit commits, remove those if possible. If you cannot afford less frequent commits, you have to tune your warming strategy to make sure it does not take as much time as period between two commits.
