title: spacy: how to get lemma-based PhraseMatcher
body: <p>I want to find a phrase words from which has the same lemma, for example if I search for "cat runs", it should match "cats ran". I tried to create a new doc with words lemma-free, but I need dependencies for some reason, but the new doc doesn't contain dependencies, and I can't match indexes of the new doc and the old doc.</p>
