I have noticed that a lot of times people ask a question and a duplicate is instantly found. It's not necessarily true that the person hasn't tried to look up the question, but it is just hard to search for certain questions on Google or stackexchange. What are some tips on searching up questions? I specifically have a concern with questions that have equations in them like $(1^3+2^3+\cdots+n^3)=(1+2+\cdots+n)^2$.
(By the way, I am not sure about the appropriate tags to use).
