The search on a date criteria is currently very basic. In the documentation, the options are:
- is exactly,
- is not exactly,
- contains,
- does not contain,
- is resource with ID,
- is not resource with ID,
- has any value (there is something in the property), and
- has no values.
Is it possible to refine the search when the field is a date (such as Dublin Core dcterms:date) where it would make sens to search with operators such as before, after and so on…
