[jira] [Reopened] (JENA-1749) Support lucene field names in jena text queries

["Brian McBride (Jira)" <ji...@apache.org>]

Brian McBride reopened JENA-1749:
---------------------------------

I suggest some clarification of the documentation is needed before this issue is fully resolved.

The documentation states that multiple fields in text queries are not supported.  That should be amended to say something along this lines of:

- normally multiple fields in a text query won't have the effect that you might expect because each triple is indexed as a separate document
- multiple fields in a text query are accepted and may be useful, e.g. where the text index has not been created by the provided Jena text mechanisms but provided by other means
- an explanation of limitations on the bound values should there be multiple fields in the a returned document

> Until recent changes made during implementation of JENA-1723, it was possible to have a Lucene text query that used Lucene field names.  With the implementation of JENA-1723 such queries result in a exception
> For example:
> {noformat}
> PREFIX  xsd:  <http://www.w3.org/2001/XMLSchema#>
> PREFIX  text: <http://jena.apache.org/text#>
> PREFIX  ppd:  <http://landregistry.data.gov.uk/def/ppi/>
> PREFIX  lrcommon: <http://landregistry.data.gov.uk/def/common/>
> SELECT * 
> {   ?ppd_propertyAddress  
>           text:query            ( "street:  the" 3000000 ) .  
> } LIMIT 1
> Cannot parse 'text:street: the ': Encountered " ":" ": "" at line 1, column 11.
> {noformat}
> This is a simplified query from a running production system that works in 3.12.0 but is failing in 3.13.0-SNAPSHOT.
> Some discussion and analysis of this issue has occurred in email:
