Note that the reasoning depth here is always 1, and the rule templates are given by the --hops parameter - e.g. 0 2 1R means there are three reformulation modules, one for rules in the form p(X,Y) :- q(X,Z), r(Z,Y) (2 hops from the subject to the object) and one for rules in the form p(X,Y) :- q(Y,X) (1 hop from the object to the subject). Here 0 means no hops is also a legal choice (just match the query with the facts in the KB). For matching with facts in the KB, we use a nearest neighbour search engine for finding the most similar facts to the query (otherwise we should have to compute the Gaussian kernel between each sub-goal and all facts in the KB all the time, and backpropagate through all these comparisons - https://arxiv.org/abs/1912.10824)
