The SPARQL client you use has altered the query via an incorrect
preamble. There's no graph IRI between "define input:default-graph-uri"
and "select", so the parser runs a bit further before it discovers that
"select" is not a valid default graph un
irely empty, it should contain at least
virtrdf: row in the answer, i.e., the system configuration graph.
Thus there may be some additional errors there.

Having sufficient number of customer requests, I can add efficient
search for IRIs by some IRI properties (e.g. free-text on them).
So far, studying each reported use case in depth reveals either some
inaccuracy/incompleteness in ontology or some way of fetching subjects
by their textual p

Note that this will not even try to remove free-text index data for this
graph.

FILTER (bif:strcontains (?haystack, ?needle))

real immediate need for that, because these functions will not be
upgraded automatically by new built-in versions, if these functions are
changed in some distant future (procedures created by user takes
priority over any built-in things).

ole storage is free-text indexed, not on per-graph
basis,
you should update free-text index, because the inverse index data of
each literal are enriched with list of graphs that contain this literal
in some quads, and renaming a graph make these data (partially)
obsolete.

Alexandre,
I've posted a procedure to find all distinct predicates that start with
some specified substring. It's trivial to turn it into a procedure to
list all distinct graphs with same filtering and make an update based on
th results.

ew and it in turn can be used in an RDF View but it is
redundand for most of applications. For typical "almost static" data, it
is more practical to write a procedure that will store all found
predicates in some dedicated "dictionary" graph and then use the graph
as usual.

hen next query can be
used:
select id_to_iri (REC_GRAPH_IID) from
DB.DBA.RDF_EXPLICITLY_CREATED_GRAPH
where exists (select top 1 1 from DB.DBA.RDF_QUAD where
G=REC_GRAPH_IID);

is neither better nor worse than any other server, because no automatic
