----------------------------------

             Summary: NullPointerException for query type 'query' without '{! ...}' syntax
                 Key: SOLR-4042
                 URL: https://issues.apache.org/jira/browse/SOLR-4042
             Project: Solr
          Issue Type: Bug
          Components: query parsers
    Affects Versions: 4.0, 5.0
            Reporter: Joel Nothman
            Priority: Minor


The 'query' query type, corresponding to NestedQParserPlugin, expects a query of form: "{! ... } ...". An empty q parameter, or a list of search terms causes a NullPointerException because NestedQParserPlugin.createParser receives a localParams == null, which is then used without checking in NestedQParserPlugin.QParser.parse().

Correct behaviour is currently ambiguous: throw a syntax error? or execute the query with the default parser?
