> The `findSynonyms` method in `Word2VecModel` currently rejects the best match a priori. When `findSynonyms` is invoked with a word, the best match is almost certain to be that word, but `findSynonyms` can also be invoked with a vector, which might not correspond to any of the words in the model's vocabulary.  In the latter case, rejecting the best match is spurious.
