It is simple:
Subclass QueryParser and override getRangeQuery and construct the correct
range query for your field type. If the supplied field name is not the one
you want to modify pass to super().
Something like:
@Override public Query getRangeQuery(...) {
if ("qdur".equals(fieldname) {
...return YourFavoriteQuery...
} else return super.getRangeQuery(...)
}
This also works with the new NumericRangeQuery and NumericField as suggested
in other mails.
