Description

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"
