When most people search the site, they're looking for a question that matches their keywords, not an answer that matches their keywords. And typically, you do not expect to see multiple search results that go to the exact same page.
Users that are not familiar with the site are unlikely to realize that they need to type "is:question" in the search box to get rid of "duplicate" results, or to filter only for questions related to theirs, which results in the Search box being not as useful as it could be.
Personally, I am getting annoyed with having to type "is:question" on every single search query I perform on a SE site, and am tired of finding "duplicate" and unrelated results in my SE searches, only to realize I've forgotten to type "is:question" in the search box yet again.
Can we automatically append
"is:question" to searches done from the Search box in the upper-right corner of the screen when no
is: keyword is specified?
This would not change the actual search functionality at all, however it would make the searches return better results in most cases instead of only returning better results in a few cases, and it would reduce the annoyance caused by having to remember to type "is:question" all the time.
