Code Ferret created JENA-1437:
---------------------------------

             Summary: text:multilingualSupport true vs false inconsistent results
                 Key: JENA-1437
                 URL: https://issues.apache.org/jira/browse/JENA-1437
             Project: Apache Jena
          Issue Type: Bug
          Components: Jena
    Affects Versions: Jena 3.5.0
         Environment: N/A
            Reporter: Code Ferret
            Priority: Minor


If {{text:multilingualSupport false}} then

    {{?s text:query ("some string" "lang:lang-code")}}

may be expected to return matches for the {{text:defaultField}} restricted to the given {{lang-code}}.

However, if {{text:multilingualSupport true}} then the same query always returns zero results owing to an improper rewriting of the query string with a field spec of:

    {{"null_lang-code:some string"}}.

OTOH, explicit mention of the {{text:predicate}} corresponding to the {{text:defaultField}}, e.g., {{rdfs:label}}, yields the expected results:

    {{?s text:query (rdfs:label "some string" "lang:lang-code")}}

Should be fixed with a proper rewriting of the _query-string_ to:

    {{"text:defaultField_lang-code:some string"}}
