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}}. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
