@dsmiley I am wondering about the AND/must case. With dismax the query:
`q.op=AND&q=black and pink&qf=title_txt_en`
turns into:
`+(DisjunctionMaxQuery((title_txt_en:black))
DisjunctionMaxQuery((title_txt_en:pink)))~2 ()`
The stopword is remove entirely and documents with black and pink are
returned.
With the Bool-Parser:
`q=({!bool must=$w1 must=$w2
must=$w3})&w1=(title_txt_en:luggage)&w2=(title_txt_en:and)&w3=(title_txt_en:pink)`
before change:
`+title_txt_en:black +() +title_txt_en:pink`
after change:
`+MatchNoDocsQuery(MatchNoDocsQuery(\"empty query\")) +title_txt_en:pink
+title_txt_en:black`
The clause with a stopword only result in no documents being returned,
before and after my change.
Wouldn't you expect that an empty clause does not have an impact on the
documents matching?
