Re: Solr equivalent of relational joins on nested documents

Might take a look at the domain join stuff in JSON facets too: https://solr.apache.org/guide/8_8/json-faceting-domain-changes.html#join-query-domain-changes ...

Re: WordDelimiter does not generate expected token

WDGF with both "generate*Parts"/"splitOn" _and_ "catenate*"/"perserveOriginal" generates a graph TokenStream structure that relies on PositionLengthAttribute to accurately reflect the graph structure. Because Lucene does not index PositionLengthAttribute, this information is lost when WDGF is used

Solr cloud: Help needed on the slowness noticed for heavy updates
