Handles subqueries of functions such as distribute, filter, map, etc. The main optimization is that in some cases, e.g. simple traversal, one overall relation can be computed and it's a simple dictionary lookup for each cycle of the function

Returns a dictionary of lists. The dict maps properties to text matches. Each list contains subjects that had the given text match for each property
