GoldFynch is capable of registering a number of common date formats (e.g. Jan 10 2017, 01-10-2017, 01/10/2017) and when it encounters a date in your documents it automatically normalizes it to a common internal format. While searching for a date in GoldFynch, the engine adjusts for how you have formatted your query and makes sure all relevant dates are included in the results, regardless of the original formatting in the document (e.g: a query for 7-1-2017 would also show documents containing 07/01/2017)
GoldFynch also goes one step further: it automatically adjusts for regional date formatting as well. It automatically pulls locale information from your browser and adjusts searches accordingly, allowing you to format dates as you normally would.
Example 1: A search for 10/05/2015 would produce the following search results depending on which locale your browser is set to:
Example 2: In the US, a document containing "5 March 2017" would be included in a search for "03-05-2017" whereas in many other parts of the world including the UK, Ireland, Australia, India and Germany, it would be included in a search for "05-03-2017".
The date query you enter is normalized in GoldFynch based on the locale settings on your browser. In some countries like Germany and Denmark, although the DD-MM-YYYY (DMY) format is more common, the YYYY-MM-DD format could also be used. Check your browser's locale and format settings.
