SOLR计数组(SOLR count of groups)

SOLR计数组(SOLR count of groups)

http://localhost:8080/solr/select?q=(apposta apposta per) OR (sue prime ore al)&group=true&group.field=grouping_field&group.limit=5

此查询返回2组第一组有1个文档，第二组有2个文档。

作为回应，我看到文件数（3），但没有组数。 我如何得到团体的人数。

http://localhost:8080/solr/select?q=(apposta apposta per) OR (sue prime ore al)&group=true&group.field=grouping_field&group.limit=5

This query returns 2 groups first group has 1 document and second group has 2 documents.

In response I see count of documents(3) but there is no counts of groups. How can I get count of groups.

最满意答案

使用group.ngroups=true来包含响应中的组数。

文档 - group.ngroups - true / false 如果为true，则包含与查询匹配的组数。 默认为false。

Use group.ngroups=true to include the number of groups in the response.

Documentation - group.ngroups - true/false If true, includes the number of groups that have matched the query. Default is false.
