Hi Matt,
smf:luceneQuery is in fact the magic property that Search the EDG is
using, but without knowing more about your specific use case I would say
'use with caution' as the magic property is really meant for use with in
SWP and has some quirks.
For example, the user must define a limit, facets are kind of a pain to
pass through, target graphs must opt in, working copies are out of
scope, and lastly all graphs in the index are queried - the only way to
narrow the scope is by providing a graph facet.
But generally speaking this should work
(params are: search term, facets, offset, limit, advanced syntax (when
true the magic property will use the input verbatim, essentially
allowing lucene operands to be utilized)
SELECT ?result ?score ?total
WHERE {
("term" ?facetFilters 0 100 false) smf:luceneQuery (?result ?score
?total)
}
If the user needs facets, we'd have to work up a more thorough example,
which would involve temp graphs.
So the alternative would be to use the textindex:query magic property
while iterating over the properties of interest.

That magic property requires a specific property to search values of,
which is not quite what I want at the moment. After digging some more,
I found smf:luceneQuery which appears to return similar results to
Search the EDG. Is there any caveats with using this magic property?

Hi Matt,
yes there are functions in the textindex namespace
(http://topbraid.org/textindex# <http://topbraid.org/textindex#>)
Open the file \server.topbraidlive.org
<http://server.topbraidlive.org>\web\2018\textindex.ui.ttlx in TBC
to see their declarations.
The name of the index for EDG vocabularies is "teamwork" - see the
Text Indices admin page.
An example call would be
("teamwork" rdfs:comment "hello") textindex:query (?subject
?score ?literal ?graph)
If you have follow-up questions, please ask here.

Hello-
Is there a mechanism like a magic property to query the freetext
index from SPARQL? I didn't see one mentioned in the TopBraid
documentation. I've used some other systems that have this feature.
Thanks.
