Description
We often come across the scene of the multi-faceted cross, For example, the SQL statement, select count( * ) from table group by A,B.
Now we slightly modified for FacetComponent, this component to be able to support the multi-faceted cross.you can facet on multiple columns, and get the count result of multi-faceted cross.
Request parameters are as follows：
&start=0&rows=0&q=:&facet=true&facet.field=user_city&facet.field=user_province&facet.limit=10&facet.cross=true&facet.cross.sep=,
The original effect is as follows:
<result name="response" numFound="479140" start="0" sum="0.0" max="-Infinity" min="Infinity"/>
<lst name="facet_counts">
<lst name="facet_queries"/>
<lst name="facet_fields">
