> Edge ngrams should be like synonyms, with all the ngrams generated from a token having
the same position as that original token. The current code increments position.
> For the text "molecular biology", the query "mol bio" should match as a phrase in neighboring
positions. It does not.
> You can see this in the Analysis page in the admin UI.
