Loads and loads of ideas are duplicated, many of which come from new members proposing the same question, some are posted even after a search.My idea is that whenever an idea is duplicated by a duplicator, they include the words that they searched the community with.
Why is this helpful?:
1) It will show others the kinds of words searched.
2) It will help the OP to learn how to search (if they are new.)
3) It will show the sort of searches for different ideas.
For the little effort it takes to implement, it will have a big impact on the ideas section, perhaps reducing the number of duplicates as members will learn to search differently.
Oh and for the record I searched: Automatic duplication, detection, duplicators include searched words. etc.
