在一个SOLR查询中获取多个字段的不同值

Question

Is there any way to query distinct values of multiple fields in single SOLR query?

I know of facet field, but it works for one field at a time.

facet:true, facet.field:XYZ

Answer 1

You can provide multiple facet.field keys in your query:

facet.field=field1&facet.field=field2&facet.field=field3

The facet.field parameter identifies a field that should be treated as a facet. It iterates over each Term in the field and generate a facet count using that Term as the constraint. This parameter can be specified multiple times in a query to select multiple facet fields .

You can also provide separate settings for each field through the f.<field>.<setting> syntax:

f.field1.facet.prefix=foo
