Hi Jan, Thanks for the reply. Our normal search times is within 650 ms. We were analyzing some queries and found that few of them were like 14675 ms, 13767 ms etc... So was curious to see whether we have some way to restrict the query to not run beyond say 5s or some ideal timing in SOLR even if it returns only partial results.
That is how I came across the "timeAllowed" and wanted to check on it. Also was curious to know whether "shardHandler" could be used to work in those lines or it is meant for a totally different functionality. Thanks!
