Yes, that is an option built into Sqlite, where we can specify the
maximum proximity between the query terms. We are not using it at the
moment but it is an option worth evaluating and comparing the results
:)

Sqlite also tells the length of the longest matching string in the
document with the query, which could be used as a metric for ranking,
need to try that out too.
