I contributed to the Tor Weekly Newsletter in the last weeks. So I looked for some questions and answers in the last seven days and picked some of them. I figured that seeing all answers or questions from the last seven days would ease this task. Is there some search mechanism which could help me here?
The Stack Exchange search does have some advanced tips (click the "Advanced Search Tips" link to see all of the options).
If I wanted to see just questions, I'd start by filtering out answers from the results, as well as closed questions:
Then I could filter further by finding questions with at least one answer, with an accepted answer, and a score of at least two.
answers:1 hasaccepted:yes closed:no score:2 is:question
To see the last seven days, click "newest" at the top of the search results so they're ordered from newest to oldest. Hope this helps.
