Info

solrconfig.xml /bjqfacet bjqFacetComponent /bjqdocsetfacet bjqDocsetFacetComponent One of these components can be added into any search request handler. The difference between the BlockJoinFacetComponent and BlockJoinDocSetFacetComponent is in the way they deal with Solr's caches. The BlockJoinFacetComponent disables queryResult cache for the request it takes part in. The BlockJoinDocSetFacetComponent uses the filter cache, which might have worse performance if commits are frequent. In most cases, the differences are negligible. Both components work with distributed search in SolrCloud mode. Documents should be added in children-parent blocks as described in indexing nested child documents. Examples: Apache Solr Reference Guide 6.0 312
document sample 1 parent 11 Red XL 6 12 Red XL 7 13 Blue L 5 2 parent 21 Blue XL 6 22 Blue XL 7 23 Red L 5 Queries are constructed the same way as for a Parent Block Join query. For example: http://localhost:8983/solr/bjqfacet?q={!parent which=type_s:parent}SIZE_s:XL&child.facet.field=COLOR_s As a result we should have facets for Red(1) and Blue(1), because matches on children id=11 and id=12 are Apache Solr Reference Guide 6.0 313
