Hi, I am using timeAllowed and a collection with shards. Docs list contains results only if QTime(query time) < timeAllowed. In other cases (partialResults=true in responseHeader) docs are empty.
/solr/collection_with_shards/select?etimeAllowed=1000&q=some_slow_query docs is empty If access a specific shard and ask for data only from it: /solr/collection_with_shards_shard1/select?shards=shard1&timeAllowed=1000&q=some_slow_query docs list contains results! (partialResults=true) If add debug=all to the collection query: /solr/collection_with_shards/select?timeAllowed=1000&debug=all&q=some_slow_query then docs list empty, but in debug info all the shards returned lists of document id's with weights. Tested on solr 8.4 and solr 8.7, change timeAllowed from 100 то 3000. Always if QTime>timeAllowed docs list empty. Results from individual shards never have time to process for the general docs list or am I doing something wrong? Can anyone confirm that when QTime>timeAllowed and count(shards)>1 you can get a nonempty docs list?
