I want to answer some questions, so that I get some reputation, at least to do the most common actions in Stack Overflow. So, I wanted to search for questions without answers, in subjects I have good knowledge about. It was not hard to find out how specific tags can be searched. So I found one question to help, and answered it.
After that, I wanted more... but I noticed there were many results marked as "duplicate" (written
[duplicate] in the subject). So, I read Search help again, to see how to search things excluding tags from the results. This is where it is failing for me.
To search a tag, we write it inside square brackets. For example, to search for threads about Bash scripts and uses, we may search for:
And to exclude things from results (tags or words), we write a "-" sign attached before it. For example, we may search for:
One more important thing: have no answer. We just add
answers:0 to our query.
So, I decided to search for Bash-related questions that are not duplicates, and have not been answered yet. The query for that can be:
[bash] -[duplicate] answers:0
But the first two results are duplicates! Look:
I tried to put the excluding term before the Bash tag, but the result is the same.
