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,
