I am still a newbie on SO, I always check is my question similar with another posted before ? If I believe there is no question similar to mine, I always ask but sometimes, some of my questions were really similar to others.
Previously, I assumed that was due to my poor English skill .... But I have no idea in some cases which keywords I should use to search for similar questions ? .
So I request some suggestions from experienced users on SO . Do you have easy ways or some useful tips of finding similar questions? I am afraid of getting my questions closed as "duplicate".
Please don't be assume this is an opinion based question because I am really troubled by it.
