Use the daterange operator to find pages that are indexed by Googlebot within the date range specified. The dates submitted must be in the Julian date format and the fractions should be omitted for this operator to work properly. Make sure you use an accurate Julian date convertor to get the correct date.
Example: daterange:2452671-2452671 columbia
Like the numrange operator, a hypen is used to separate the two dates. This operator is useful for narrowing down all search results to a certain date like in the above example.
The numrange operator requires at least one proper search term and can be combined with other operators.
An additional note: Use Google's advanced search to locate only fresher, up-to-date information. It's easier that way.
