New description:
Now that we store both the stemmed and unstemmed forms of each word in the
database, it might be nice to add a new stemming mode to the query parser
which
takes each word in the query and generates an "OR" query for it, with two
parts;
one being the unstemmed form and one being the stemmed form. This would
mean
that each query would match any document with words which match the
stemmed
form, but would give documents with the unstemmed form a higher weight.
We might call this option "STEM_BOTH", or some better name that someone
other
than me can think of.
