New Thread - list similar Threads

[gremlin2412]

I am looking for an extension, which when creating a new theme automatically looks for similar themes and these lists. This allows members to see whether a question was already answered, and duplicate topics on a subject to be avoided.

Sorry for my "Google Translator" English :erm:
