33788	Add support for PostgreSQL pg_trgm strict_word_similarity	Matt	Matt	"PostgreSQL's documentation is somewhat unclear when describing the `word_similarity` function and does not force the extent boundaries to be the true word boundaries.

See here for wider discussions on the topic: https://www.postgresql.org/message-id/CAPpHfdudo%2B%3DEwzWgyOyKN96e4s0Vrh_%2BA-Yu%3D_L3O1miPVz4Fw%40mail.gmail.com & https://stackoverflow.com/questions/46966360/postgres-word-similarity-not-comparing-words

Out of this came the new `strict_word_similarity` function which does respect word boundaries. 

Adding a django API for this function would give more options for performing fuzzy text matching. This could also be implemented as an extension to the existing `TrigramWordSimilarity`.
