Here's one solution. It doesn't allow you to specify particular date ranges but is better than nothing.
tl;dr - Use a special kind of bookmark that takes a your search terms and returns Bing results with an optional date filter (past .
Mostly copied from my answer here: http://www.bing.com/blogs/webmaster/f/12248/t/652228.aspx?pi239031353=8#
The basic answer is to type &tbs=qdr at the end of a url after searching, but this can be made a lot easier with a minute's work.
Firefox (and maybe the others) have a type of bookmark that activates whenever you type a keyword in the address bar. Mine is set up so that I only have to type b
in the address bar followed by my search. So,
b no date filter will automatically go to bing and search for
no date filter. Additionally, it puts
tbs=qdr in the final url so the date option is always available.
To do this in firefox, create a new bookmark (ctrl+b to open bookmark viewer, right click -> new bookmark). Set 'Location' as
http://www.bing.com/search?q=%s&tbs=qdr
and set 'Keyword' as b or anything else you'd like. Now you can search Bing as described above. If you automatically want to restrict to a particular date range, instead use the following for bookmark 'Location'.
http://www.bing.com/search?q=%s&filters=ex1%3a%22ez0%22&tbs=qdr - any time
**http://www.bing.com/search?q=%s&filters=ex1%3a%22ez1%22&tbs=qdr** - past day
**http://www.bing.com/search?q=%s&filters=ex1%3a%22ez2%22&tbs=qdr** - past week
**http://www.bing.com/search?q=%s&filters=ex1%3a%22ez3%22&tbs=qdr** - past month
Hope this helps. It really is a pain to only sometimes get the date option. With this solution, one can easily perform searches with only keyboard input (no manually opening bing, clicking on the search box, etc.). The actions: 'ctrl+t, alt+d, 'b <search string>'
are all you need to open a new tab, focus on address bar, and query bing so that it gives you results with a date option.
(An aside: the bookmark hotkey trick can be set up to work with other searchable sites: wikipedia, google, allmusic, youtube, dictionary, ..., and each has their own hotkey. ex. 'w Annapurna' redirects to http://en.wikipedia.org/wiki/Annapurna. It's just
a lot easier to type that than to navigate to wikipedia and then search.)
