Comment (by olly):

 Some thoughts on a plan of attack (from an IRC discussion):

 I'd suggest first just getting the parser to generate `<term> OR
 <stemmed_term>` and worrying about the best way to weight it once that's
 working.

 The parser is in `xapian-core/queryparser/queryparser.lemony` and uses the
 lemon parser generator )which is similar to yacc and bison).

 I think this probably wants to happen in the same places that auto
 synonyms do, so look at `Term::get_query_with_auto_synonyms()` to start
 with.
