I'm not offended at all. I'd love to see a new search module but at the
moment I can't work on it anywhere near enough of the time. A situation
that will continue for several months yet.

As currently both mg and sword have the same limitations (regarding
positional information) it would be sensible to adopt mg as the search
engine within sword. When, if?, sword moves to a more flexible positional
format then would be the time to reconsider the issue.

However, mg isn't available for all platforms. Early releases suffered
Sun-endian issues. It might not be to other people taste. Perhaps a
wrapper layer is needed. Then those working on or with other search
modules (*) can interface them to sowrd instead of mg.

(*) As it happens I have one but it's proprietary and commerical. I'd like
to be able to exploit that myself as it has a general position pointer
scheme (field, paragraph, sentence, word within sentence, character within
word). Sadly I can't release it; I don't own the rights to it.
