One or two questions of mine are correctly marked as duplicate in the community.

How can I find the duplicate of my question before I post the question in the site?

Because it is not easy to find similar questions by simple search in the community.

Unfortunately, it's really just mostly searching. You can limit your search using tags—just include the tag name, surrounded by brackets, when doing your search (e.g., "[phd] grades"). That helps limit the search. You can also use "is:question" to only search only questions (e.g., not answers). Past that, it's just making sure you use good search terms. Good luck!


Note that when you start typing a new question title into the "Ask a Question" box, it lists some possible duplicates immediately underneath. Read through these questions to make sure you are not asking a duplicate.

This is too long for a comment ...

Before asking a question it is best to have a quick search for similar questions. If you don't find a match and then ask a question that eventually gets closed as a duplicate, it is not an awful thing. While most closed questions eventually get deleted, duplicates are special and tend to get left on the system. This means that a duplicate question makes finding the original question a little easier for the next person.


In addition to all the correct answers, I have to agree that the search features of StackExchange are not exactly inspiring. I myself often think "I think we have seen this question before", but when I go and look for it, I can't find any duplicate. It always seems to me that I am only able to find a duplicate if I remember at least some words of the question title.

As such, for a new user, I would propose to do a quick search, and if you can't find a clear answer, just go ahead and ask your question. If it is closed as a duplicate, you at least know where to look. Always remember that a question being closed is not an insult, and does not cost you reputation on the site.
