Post-Processing: Date Filter

When the search has finished the Search Results page provides two different ways of filtering results by date, under the Pages Last Modfified option:

1. Select a time period from the drop-down menu: in the past month, in the past 3 months, in the past 6 months, in the past year, more than 1 year ago, more than 2 years ago, more than 5 years ago.
   
   OR
   

2. Enter a date range in the text boxes provided.

WebCorp uses a series of heuristics to find the last modified date of web pages, going beyond the techniques used by standard search engines. On the results page you will be presented with the source of the date, which will be (in order of reliability) 1:Server Header, 2:Date Metatag, 3:Author-Specified Modification Date in Document Body, 4:Copyright Date, or 5:Date in URL.

You are also given the option to sort the resulting concordances by date.
