I've been using DuckDuckGo as my main/default search engine for about two years. Overall, I'm very satisfied and have no plan to return to the big "G".
Thank you for adding "Search by date" options. Regarding these, I humbly request that more choices be added.
Ideally, I'd love to see more open-ended options (such as " x months" that allows the user to fill in any number of months, or "from date x to date y " that allows the user to restrict results to a specified range of dates. Would it, perhaps, be possible to include something along these lines in the search syntax?
Barring that, please add further choices to the drop-down menu (such as "6 months", "1 year", and "2 years").
Please let me know via comments if any of this is already possible. Thanks again.
