 It was Montague’s strategy to apply to all expressions of a category the most general approach, and narrow this down, when required, by meaning postulates (and, in some cases, logical decomposition). So initially, find is also considered to be a relation between an individual and such an abstract entity, but some meaning postulate restricts the class of models in which we interpret the fragment to only those models in which the relation for find is the (classical) relation between individuals.
