Perform MongoDB queries

This magic property integrates SPARQL with MongoDB using triples that link a subject with its MongoDB ID via the http://www.franz.com/hasMongoId predicate. I.e., 

?subject <http://franz.com/ns/allegrograph/4.7/mongo/find> '{JSON query expression}' .

will perform a MongoDB query for ` ` to return object IDs and then it will use these IDs to link to the desired triple via http://www.franz.com/hasMongoId.

You can also bind the MongoDB ID of the triple found using: 

(?subject ?mongoID) <http://franz.com/ns/allegrograph/4.7/mongo/find> 'expression' .

By default, only the '_id' slot is returned for any matching document. You can use the following form to include a selector specification to choose any additional document fields you would like to return from MongoDB 

(?subject ?mongoID) <http://franz.com/ns/allegrograph/4.7/mongo/find> ('expression' 'selector') .

See the mongo:slotValue magic property definition or SPARQL filter function for documentation on how to fetch these slot values using ?mongoID and bind them to SPARQL variables.
