$resultset->refine $query
Returns a new query which is a modification of the current query.
The existing query is augmented in the following way,
depending on the type of $query
:
If $query
is a hashref,
it is added as an AND restriction.
If $query
is an arrayref,
it is added as a local OR restriction (which is not implemented yet).
