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

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`.
'''Note''': this is a PostgreSQL 11+ feature.
