It really depends on the users voting on the definition of "duplicate," which is why this is a democratic process.

By definition, however, it means that the general question you've asked have already been asked and answered, and the answer for the given question *should* work for you.

If the duplicate target does *not* answer your question, you may edit your question to make it sufficiently different, or point out *why* the duplicate target does not answer your question. Optionally, you may appeal your case on meta, where the community at large (or one of our <s>gods</s> moderators) will decide on your case.
