Rupert Westenthaler resolved STANBOL-607.
-----------------------------------------
Resolution: Fixed
fixed with #1337141
> SolrYard should use quotes instead of AND for multi word TextConstraints
> ------------------------------------------------------------------------
>
> Key: STANBOL-607
> URL: https://issues.apache.org/jira/browse/STANBOL-607
> Project: Stanbol
> Issue Type: Improvement
> Reporter: Rupert Westenthaler
> Assignee: Rupert Westenthaler
> Priority: Minor
> Fix For: 0.10.0-incubating
>
>
> 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"))
