You might generalize "Knowledge Bases" to "Similarity Analysis". It is possible, for example, to use the stored idea of a "fork" in chess in other games, or on the battlefield. This, in turn, generalizes to categories and symbols - "when are two things the same" is "when are they in the same category" is "when do I use the same word". And this, in turn, shares a fuzzy boundary with perception and search trees - that is, an analogy is a kind of high-level perception, and that analogy may be created by a search tree that tries to unify low-level similarities in all the possible ways. (Actually, I don't know how symbols and analogies work.)

Nevertheless, I think that "Similarity Analysis" remains distinct. That the various strategies may be composed of each other (at different levels) does not obviate their usefulness as heuristics.
