Hi, I'm trying to understand what's going on with the combination of: * Solr 8.1.1 * edismax parser * qf with multiple fields specified (each of which has type text_en_splitting, some of which are multiValued) * unified highlight method * query with two terms * results where the two terms match against _separate_ fields
when I make both of the two query terms _required_. (Sample values for the query parameters to start with: "q":"scope national" "fl":"id,last_updated,slug,status,title,acronym,publisher,description,widgetable,sissvoc_endpoint,owner,[explain]" "defType":"edismax" "qf":"title_search^1 subject_search^0.5 description^0.01 concept_search^0.5 publisher_search^0.5" "hl":"on" "hl.fl":"*" "hl.method":"unified" "hl.snippets":"10" ) So far, so good: results are correct, and highlighting is correct. In particular, for a result in which there is a match for "scope" in one field (concept_search) and for "national" in another (publisher_search), I get a highlighting result for "scope" in concept_search and for "national" in publisher_search. (I also get a highlight for another field concept_phrase which has the same content as concept_search but with string type.) All good so far. But now if I change the query from "q":"scope national" to "q":"+scope +national" my results still (correctly) include the result in which there was a match for "scope" in one field (concept_search) and for "national" in another (publisher_search), but now there are no _highlights_ for that result! What is even more counterintuitive is that if I now also set "hl.requireFieldMatch":"true" the highlights for the concept_search and publisher_search fields (but not the concept_phrase field) come back!
