Possible?: Use "Advanced Search" to retrieve records created since a certain date

I'd like to be able to retrieve all records created since 12/2/2010, but when I select "Date Created" in the "Advanced Search" section of BiblioWeb's Search/Browse page, type ">12/2/2010" into the field, and click the "Search" button, I am presented with this error message:

EXCEPTION: DBISAM Engine Error # 11949 SQL error - Type mismatch between column 'Date_Created' and expression '/' in WHERE or JOIN clause

Please advise,
Thanks in advance,

Please use the internation date format in single quote. For example: > '2010-12-02'
