One option of course would be to store all document content as triples
to Jena, but that might lead to other trouble since Jena is not meant to
be used that way.

I'm not sure there are any widely-known best practices for that pattern, but I
defer to Osma and Chris.
My limited understanding of Lucene implies that only one JVM at a time can lock
an index, but the last time I looked at that question was years ago, so take
that with a bucket of salt.

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?
