Subject [jira] [Commented] (SOLR-10078) "Unknown query type:org.apache.lucene.search.MatchNoDocsQuery" error with Solr v6.3
Date Mon, 02 Oct 2017 11:59:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-10078?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16187898#comment-16187898
] 

Bjarke Mortensen commented on SOLR-10078:
-----------------------------------------

When https://git-wip-us.apache.org/repos/asf?p=lucene-solr.git;h=a3fc7ef was committed, a
case for MatchNoDocsQuery was made in ComplexPhraseQuery.rewrite:
{{} else if (qc instanceof MatchNoDocsQuery) {}}

Will it be needed to make the same case in ComplexPhraseQuery.addComplexPhraseClause when
the child clauses are iterated?

> I did NOT have this error in Solr v6.1 so something has changed in v6.3 that is causing
this error.
> Steve Rowe thinks it may be related to https://issues.apache.org/jira/browse/LUCENE-7337
> Hoss' initial thoughts:  "i think the root of the issue is that the way those fuzzy and
prefix queries are parsed means that they *may* produce an empty boolean query depending on
the contents of the index, and then the new optimization rewrites those empty boolean queries
into MatchNoDocsQueries -- but the highlighter (which uses hueristics to figure out what to
ask each query -- based on it's type -- what to highlight) doesn't know what to do with that.
 i'm really suprised the highlighter throws an error in the "unexpected query type" code path
instead of just ignorning it."
