Hi. Can you make sure you don’t exceed qcache_max_bytes and if you don’t provide more details on how to reproduce the issue (best as an issue on github) as we have an automated test covering it and I tested it manually and qcache_thresh_msec works fine for me.
you’re right - but with 18 local indexes the query times are different on every query (same keywords) - sometime index1 is the fastest, some the slowest. So caching with distributed local indexes make no sense…
it is planed in future to cache the hold distributed index?
we have no such features at our backlog as general http proxy caches such requests well and local index cache stores raw documents and provide them back for regroup or rerank and these operations perform at local index level
however you might create ticket at github to be informed on issue progress.
