Instance Method Details

#show_only_other_collections_of_the_same_collection_type(solr_parameters) ⇒ Object

Solr can do graph traversal without the need of special indexing with the Graph query parser so use this to compute both the parents and children of the current collection then exclude them See solr.apache.org/guide/solr/latest/query-guide/other-parsers.html#graph-query-parser
