Hi Osma!
yes sorry I was talking about jena-text. It would really be great to be
able to use one tool for all RDF and text index queries. I'll check how
JIRA works and what is submitted there already.
Br,
Mikael

Hi Mikael!
I assume you are talking about using (or not) jena-text here?
If needed features such as result highlighting are missing from
jena-text, please consider creating one or more JIRA issues on
issues.apache.org so that they can be discussed and possibly addressed
in future versions. Also pull requests for jena-text are very welcome!
The idea with jena-text is to have text index functionality built in
to the RDF store, so that there is no need for an application to
maintain an external Lucene (or similar) index. It obviously exposes
only a subset of Lucene (or Solr, elasticsearch and the like)
capabilities, but the subset has expanded over time according to
users' requirements.

Ok thanks! Looks like we need result highlighting too so seems to be
best so stick with separate Lucene at this time.
So basically I'm duplicating all rdf data in Lucene index so not the
most elegant solution...

Hi,
we are making a document search system which consists of document
database for storing text and Jena for storing all document metadata
(DCMI terms). We need to find documents by boosting certain metadata
fields over content, and also find similar documents with custom
boosting of fields. Search is targeted to content and metadata. In
search results we need to return all related metadata stored in Jena.
I have already made a separate Lucene index for content and some
metadata fields and just noticed ARQ extension can do that (yes,
should
have read Jena documentation first). But is it possible to boost
Lucene
fields for search and similar when using ARQ?
At query time:
The query string can be any Lucene syntax so the "^" operator should
work.
At index build time through ARQ:
Sorry - don't know for sure ; it doesn't look like it.

Also found this SIREn:

Does anyone have any experience on SIREn, how does it compare to ARQ?
Thanks,
Mikael
