ids request to shard with star query are slow I have a distributed solr environment and I am investigating all the request where the shard took significant amount of time. One common pattern i saw was all the ids request with q=*:* and ids=<some id> took around 2-3sec. i picked some shard request q=xyz and ids=<some id> and all of them took only few milliseconds.
I copied the params and manually sent the same request to that particular shard and again it took around 2.5 sec. But when i removed the query (q=*:*) parameter and sent the same set of params to the same shard i got the response back in 10 or millisecond. in both cases the response had the document i am looking for. took 2-3 sec ------------- q=*:*& qt=search& ids=123& isShard=true took 20ms --------- qt=search& ids=123& isShard=true In my understanding ids param is used to get the stored field in a distributed search. Why does the query parameter (q=) matter here ?
