Hi, I have trouble understanding why the first query is slow and second
one is fast. Using Jena Fuseki 3.4.0.
So I want to get all resources that reference , and their
types:
SELECT * WHERE

Hi Mikael!
Fuzzy search is a basic Lucene feature, just like prefix searches.
You should be able to use it directly via jena-text using a query like
?s text:query "word~"
or
?s text:query "word~1"
There is AFAICT nothing to implement on the jena-text side as this
alre
in ES, so it can also be queried
outside Jena. If you had the documents + jena-text indexed metadata in
ES, you could use ES facilities for similarity search and still do
some things in SPARQL.
