This should work (C++ version):

    Xapian::TermIterator i = db.spellings_begin();
    i.skip_to(word);
    if (i != db.spellings.end() && *i == word) {
        // Already in the dictionary.
    }

You will currently be offered a suggestion if there's a more common
variant within the specified edit distance.  Probably such a variant
should need to be significantly more frequent to be offered.  This
