The query operators "..", ">" and "<" apply to numbers and dates. For instance, you can specify a range of nights as:
19 01 2003 .. 21 01 2003 or 19 Jan 2003 .. 21 Jan 2003
By the way, dates can be entered with any separators as long as they follow the european convention (DD MM instead of MM DD).
More information on query operators is given in the WDB help page.
