Comment:

 The `topterms` template is just a thin wrapper around the `query` one:

 {{{
 $set{topterms,$or{$query,$ne{$msize,0}}}$include{query}
 }}}

 The problem here is that checking `$msize` forces the query to be parsed
 and the match run, and that means that some things set up in the `query`
 template (the term prefixes at least) end up ignored because they're now
 set too late to make a difference.

 I think we probably need to move at least the `$msize` check into the
 query template.

 The issue with `opensearch` and `xml` is that they don't have the code to
 set up the term prefixes.  So they're only searching the body of
 documents, whereas the `query` template searches title and topic too.  It
 would be more consistent for them to default to the same fields.
