The previous answer shows how to start to address the problem raised, but I get the impression that the question which has been asked is the wrong question.

Does the hash contain these 'thousands of words' as a key or a value? It would have been useful if the original question could have contained a small hash showing the data layout.

Perhaps the real question should explain why you have such a hash and why you're looking for string matches?
