superman369 commented on SOLR-13156:
------------------------------------
h4. [~mkhludnev], I do a test in solr7.7. Limiting field facet with certain
terms via \{!terms} is work use facet.sort=count, but facet.limit,
facet.offset does not work. What's wrong?
h4. for example:
h4.
facet.field=\{!terms='1453,1452,1248'}location.authorIds&facet=true&facet.limit=1&facet.offset=1,
facet result
h4. "location.authorIds" has 3 items. I think it should have one item.
Could you help me? Thank you very much!

> When I'm doing limiting facet keys with \{!terms} it doesn't take into
> account sorting.
> First query not limiting the facet keys:
> {{facet.field=title&facet.sort=count&facet=on&q=*:*}}
> Response as expected:
> {{"facet_counts":\{ "facet_queries":{}, "facet_fields":\{ "title":[
> "book2",3, "book1",2, "book3",1]}, "facet_ranges":{}, "facet_intervals":{},
> "facet_heatmaps":{}}}}}
>
> When doing it with limiting:
> {{facet.field=\{!terms=Book3,Book2,Book1}title&facet.sort=count&facet=on&q=*:*}}
> I'm getting the exact order of how I list terms:
> {{"facet_counts":\{ "facet_queries":{}, "facet_fields":\{ "title":[
> "Book3",1, "Book2",3, "Book1",2]}, "facet_ranges":{}, "facet_intervals":{},
> "facet_heatmaps":{}}}}}
> I've looked at the code, and it's clearly an issue there:
>
> org.apache.solr.request.SimpleFacets#getListedTermCounts
>
> {{for (String term : terms) {}}
> {{ int count = searcher.numDocs(ft.getFieldQuery(null, sf, term),
> parsed.docs);}}
> {{ res.add(term, count);}}
> {{}}}
>
> it's just basically iterating over terms and don't do any sorting at all.
