The index is simply URI and text string, with no concept of which graph
it comes from.
What you may wish to do is:
SELECT ?s
{ ?s text:query (rdfs:label 'word' 10) ;
rdfs:label ?label
}
which looks the text query up and then checks to see if the URI returned
actually does have a triple of that property.
So:
SELECT ?s
{
GRAPH :graph {
?s text:query (rdfs:label 'word' 10) ;
rdfs:label ?label .
}
}
Not exactly the same but similar.
Otherwise, you'll need to create separate indexes and have separate
property functions to access each one.

I have a TDB dataset composed of multiple named graphs (i.e. one per
'vendor') which I would like to index using the text search module
and then search using named graph semantics. Some of my SPARQL
queries reference all graphs and some reference just a single graph
so splitting the data into multiple datasets each with a separate
Fuseki service endpoint wouldn't work well.
Any advice on how to assemble such a solution would be welcomed and
appreciated.
Thanks,
