Elie Roux commented on JENA-1388:
---------------------------------
Well, I'm not sure how you would handle blank nodes easily. In our data we have
{noformat}
bdr:P2053 a :Person ;
:personName [ a :PersonPrimaryName ;
rdfs:label "a name"@en
] .
{noformat}
and we want "a name" to be fully associated with bdr:P2053 in the Lucene
indexes and queries, not with a blank node. In our system, all these triples
would be in the same graph so having a per-graph query would solve this issue,
but of course it's specific to our way of handling graphs.
> Lucene text search across multiple fields ("AND") yields no results

> Project: Apache Jena
> Issue Type: Bug
> Components: Text
> Affects Versions: Jena 3.4.0
> Environment: CentOS 7.3, OpenJDK 64-Bit, v1.8.0_141-b16
> Reporter: Vilnis Termanis (Iotic Labs)
> Assignee: Osma Suominen

> Searching across two Lucene text indexed fields produces potentially
> unexpected results. (The following assumes that the string supplied to each
> field does match and is tied to the same uid/subject.)
> # A query across two fields with *OR* produces two equal rows
> # The same query but with *AND* produces no rows
