Solr 7.5 Limiting Facet with certain term cannot order by count?

Question

我想在 Solr table 作者上对 location.authorIds 字段进行分面，但也用某些术语限制分面。

我这样做了，就像在 Solr 7.5 教程中一样，http://lucene.apache.org/solr/guide/7_5/faceting.html，但是从 Solr 返回的结果没有按计数排序，有人知道为什么吗？

这是我的 Solr 查询：

http://127.0.0.1:8080/solr/authors/select?q=*:*&fl=handle&fq=search.resourcetype:2&start=0&rows=0&facet.field={!terms=27J001,J027,J132,J107,J225,J141,J092,J191,J224,J198,J062,J051,J143,J208,J119,J031,J057,J030,J134,J144,J158,J058,J181,J222,J153,J002,J203,J012,J045,J014,J186,J011,J064,J065,J147,J112,J192,J167,J066,J135,J096,J082,J075,J009,J193,J217,J168,J121,J059,J034,J213,J148,J169,J133,J013,J161,J093,J097,J162,J021,J170,J171,J083,J187,J178,J077,J194,J078,J098,J067,J047,J052,J172,J005,J113,J079,J099,J114,J100,J115,J068,J173,J084,J214,J101,J060,J025,J122,J195,J188,J196,J116,J102,J159,J197,J029,J094,J123,J053,J043,J189,J124,J015,J085,J174,J004,J044,J182,J088,J007}location.authorIds&facet=true&facet.sort=count

这是结果，您可以看到它没有按计数排序。

在我对代码进行了测试和调试之后，我可以清楚地看到，这是代码中的一个错误。

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);
}

这显然是错误的，因为它只是遍历列表并按照您在查询参数中指定的顺序提供计数。

我创建了一个 Solr 问题 - https://issues.apache.org/jira/browse/SOLR-13156 - and provided the patch. It was committed 很快就会在 Solr 中可用
