Before posting a question on the forum, I check for answers related to my question. As always, I do not find any answers pertaining to my topic and ask my question. Nevertheless, a lot of my questions have been marked as duplicate.
My first question is "how do I better search for answers so that I do not keep asking duplicate questions?"
My second question is "why should we keep marking questions as duplicate if people cannot find the original question to begin with?" I mean, if people can ask the same question without using the same terms/wording, then it would make sense to keep both versions of the question and not allow the "back end" to destroy it.

, because most users new to LaTeX run in to the trap ;-), therefore a high chance of Duplicate. More sophisticated (sorry for that term) features are asked most time only once, requiring TeX internals, which is not needed for the everyday user of LaTeX. Posting a duplicate is no stigma and does not change the reputation (as far as I know), otherwise I refer to Werner's answer.
