Yuki Yano created SOLR-11470:
--------------------------------
Summary: Negative queries always return "No Results" with rq
parameter.
Key: SOLR-11470
URL: https://issues.apache.org/jira/browse/SOLR-11470
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: search
Reporter: Yuki Yano
h3. Overview
Negatives queries (ex. {{q=NOT foo}}) always return "No Results" with rq
parameter (ex. {{rq=\{!rerank reRankQuery=bar\}}}). This is because
{{QueryUtils#makeQueryable}} doesn't consider RankQuery and fails to modify
wrapped pure negative queries to searchable ones (ex. modifies {{q=NOT foo}} to
{{q=(NOT foo) AND \*:\*}}). Pure negative queries are rewritten as
{{MatchNoDocsQuery}} by {{BooleanQuery#rewrite}} and this results in
{{numFound="0"}}.
h3. How to reproduce
# Prepare solr server according to [Solr
Tutorial|http://lucene.apache.org/solr/guide/7_0/solr-tutorial.html].
# Search with {{/solr/techproducts/query?q=NOT foo}}. This returns 52 documents
as the result.
# Search with {{/solr/techproducts/query?q=NOT foo&rq=\{!rerank
reRankQuery=bar\}}}. This returns 0 document (52 documents are expected
though...) as the result.
h3. How to fix
Add new API {{RankQuery#getMainQuery}} to be able to get the wrapped query from
{{RankQuery}}, and use it in {{QueryUtils#makeQueryable}} to fix the original
query if given argument {{Query q}} is instance of {{RankQuery}}.
