> 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.
