The only difference between add_term and add_posting is that add_posting
also adds positional information.

My only thought is that it might be that you're stemming postings but
not terms, and then stemming at search time, or something like that.

A good way to look at what is really in the database is to use the
"delve" utility, which you can find in xapian-core/examples.  So
for example you can list which documents index term "TERM" like this:

delve -t TERM DATABASE

If that doesn't resolve it, try to produce a small, self-contained
example showing the problem e.g. create a database, add a document with
some terms, and then fail to find that document when searching for one
of them.
