Solr 3.4 group.truncate 不适用于构面查询
当使用分组与group.truncate=true时，以下简单的方面查询：
facet.query=Monitor_id:[380000 TO 400000]
没有给出与等效过滤器查询的nGroups结果相同的数字：
fq=Monitor_id:[380000 TO 400000]
我认为他们应该是相同的 - 来自 Wiki 页面：
group.truncate: If true, facet counts are based on the most relevant document of each group matching the query.
我做错了什么？
如果我关闭group.truncate，那么计数是相同的，正如我所期望的 - 但不幸的是我只对分组结果感兴趣。
谢谢！
When using Grouping with group.truncate=true, The following simple facet query:
facet.query=Monitor_id:[380000 TO 400000]
Doesn't give the same number as the nGroups result for the equivalent filter query:
fq=Monitor_id:[380000 TO 400000]
I thought they should be the same - from the Wiki page:
group.truncate: If true, facet counts are based on the most relevant document of each group matching the query.
What am I doing wrong?
If I turn off group.truncate then the counts are the same, as I'd expect - but unfortunately I'm only interested in the grouped results.
Thanks!

这不是一个错误，而是一个缺失的功能，如 SOLR-2863。正如问题 Lucene 需要支持矩阵分组面计数中所述。可以在 LUCENE-3097 中跟踪此功能。
This is not a bug, but a missing feature as has been described in SOLR-2863. As described in the issue Lucene needs to support matrix grouped facet counts. This feature can be tracked in LUCENE-3097.
