> Currently a Text constraint for rdfs:label containing "The Book of Three" is encoded like
>     (_\!@/rdfs\:label/:The) AND ((_\!@/rdfs\:label/:Book) AND  (_\!@/rdfs\:label/:of) AND(_\!@/rdfs\:label/:Three))
> however Solr/Lucene allow to use quotes for multi word searches. So the correct way to encode this query would be
>     ((_\!@/rdfs\:label/:"The Book of Three"))
> This need to be fixed in the "org.apache.stanbol.entityhub.yard.solr.query.QueryUtils#encodeQueryValue(..)
> NOTE: The impact of this change for Wildcard queries need to be further investigated
> e.g  take a query "Frankf* am Main" currently encoded like
>     (_\!@/rdfs\:label/:Frankf*) AND ((_\!@/rdfs\:label/:am) AND  (_\!@/rdfs\:label/:main))
> would than result in
>     ((_\!@/rdfs\:label/:"Frankf* am Main"))
