Brian McBride commented on JENA-686:
------------------------------------
To meet our local needs I have attempted to address this in three steps:
1. Created an external text indexer that produces Lucene documents that
contain all the indexed properties for a resource.
2.Create an extension point in jenatext to allow an assembler to specify the
class that is used to create the Lucene document that is indexed when a dataset
is updated.
3. Create an implementation of TextDocProducer that also creates a Lucene
document containing all the known indexed properties for a resource and uses
update rather than add.
I have done a local solution, because I'm not clear on how best to implement a
solution that supports both conjunctive searches and the ability to restrict
searches to a single graph.
> Add support for cross field conjunctive queries in jena-text

> Key: JENA-686
> URL: https://issues.apache.org/jira/browse/JENA-686
> Project: Apache Jena
> Issue Type: Improvement
> Components: Text
> Affects Versions: Fuseki 1.0.1, Jena 2.11.1
> Reporter: Brian McBride
> Attachments: TestDatasetWithBatchProducer.java
>
>
> We have a project where we are doing text search on addresses and wish to do
> jena text queries like "city:liverpool AND street:green". These queries
> return no results, whilst queries like "street:green AND street:lane" work
> fine.
> The reason is that jena text indexes each property in a separate Lucene
> document, so there is no Lucene document matching city:liverpool AND
> street:green, there are two documents, one for each property.
> Given the scale of our data, we really want to do the conjunctive query in
> Lucene and not two separate queries and then a filter in SPARQL.
> I will attach a test case from an attempt to solve this for us to illustrate.
