> Key: SOLR-13337
> URL: https://issues.apache.org/jira/browse/SOLR-13337
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Components: SearchComponents - other
> Affects Versions: 7.7
> Environment: Linux 64bit debian
> 20-node cluster
> Reporter: Morten Bøgeskov

>
> When the TermsComponet distributes across all shards, all (terms.limit=-1)
> are returned.
> This ought not to be needed when using terms.sort=index.
> When using terms.lower=a in small test base (400k entries) it took 8.5-11.5s
> to do a
> /terms?terms.fl=register&terms.sort=index&terms.lower=a I did not try it on
> production data (10x)
> I do get the reason for getting all terms when sorting by count, however when
> sorting by index, no more than the terms.limit number rows is required from
> any shard. Most likely some will get discarded due to presence in more than
> one shard. Given no term.min/maxcount (which definetely throws a spanner in
> the works).
>
> I've attached what I think would do the trick.
> I haven't actually tested the patch (it compiles, however some other files in
> the checkout I have doesn't: ant compile, javac: "error: cannot find symbol")
>
> Might be somewhat related issue (SOLR-2908). I didn't quite get the more
> subtle information in it.
>
>
> Tested by
> * applying patch to 7.7.1 (the one we use in production)
> * start up on spare server (during off house on test system)
> * add a replica from a collection (so that it'll serve requests)
> * request /terms?terms.fl=phrase.title&terms.sort=index&terms.lower=a from
> the instance ~30 ms
> * request the same from another unpatched instance ~17k ms
> * both returned same result
> * added terms.mincount=2 to the quick request. failed with out of memory
> * restarted sever with more memory (.5g -> 8g)
> * request completed in ~18k ms
>
> I don't see how I'm supposed to unit test the functionality given it requires
> a cloud instance and sufficient data to give measurable difference with or
> without extra request arguments.
