Reason I'm asking this is that now, with external doxument index, we can't do any paging which results very slow and heavy queries on document index. We have to read all results from external Lucene, because we need to apply filtering to result by metadata fields which are store in Jena.

For example we have query like
content matches "language AND technology" & metadata matches dcterms:created > "2019-01-01"

Not sure. Reading Jena text documentation, it states that external document contents can be added into Jena text index.

Just not sure how this should be done in practice. How to handle concurrency, and how exactly add documents so that we could make sparql queries that target content and metadata same time, preferably with some weights.

But it's fine for us to use single Lucene index for all data.

Are you asking how to use an extant Lucene index with your text documents in it for Jena's text index as well?

Hi,

Our system stores documents with separate rest API and document id's are stored, along with document metadata, to Jena db. we would like to make text queries that target both the document contents and meta data.

Is there a recommended/supported way to make this happen on Jena and Lucene?
