Perform AllegroGraph freetext expression queries.

Like the fti:match magic property, this magic property can be used in several ways: 

  ?subject fti:matchExpression 'expression' .

will perform a freetext expression query for 'expression' and bind ?subject to the subject of each triple found. 

  (?subject ?textObject) fti:matchExpression 'expression' .

will act as the first but will also bind ?textObject to the object of the triples found. 

  ?subject fti:matchExpression ( 'expression' 'indexName' ) .

and 

  (?subject ?textObject) fti:matchExpression ( 'expression' 'indexName' ) .

will perform a freetext expression search using only the specified index.
