Thanks for the thought, good point, I suspect almost everyone gets caught by the quicksearch silently dropping query syntax (we filed a bug report about this http://clangers.collectiveaccess.org/jira/browse/PROV-1894
). But no, this is on the object searches (both basic search via query syntax and advanced search via form). ElasticSearch does not seem to handle #. If you are using ElasticSearch and you get the exact date result, please let me know!
