Description

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?
