It also saves on storing word position information in the index file, which
is the other solution. It is pretty efficient to narrow down the search
results afterward, unless the individual words commonly appear in the same
verse but not adjacent to one another (such as a search for "and God the"
or something). Storing word position in the index file solves this
problem, but increases the index size.
