please tell me how to see the same posts with others we are confused to look for it, and it is very difficult to find one by one
I don't really understand what you are saying, but as far as I understood, you are trying to avoid plagiarism /or you are hunting for copy-pasters??/
Both cases use the search engine, put part of the text in between " and search for it.
Example:
If you search for : this is my sentence
You write in the search field " this is my sentence"
You probably gonna get the result you are looking for.
But don't rely on solely on the forum Search engine. Use Google too. Write the same sentence in Google, you may be surprised how many hits you gonna get.
