Why does my Search not work for my email?

Question

I enter the word "address" and it does not bring all the emails I have with the word "address" in the subject or body. They exist and the search engine does not find. I have read the advance search and tips, does anyone else have this issue?

Answer 1

I haven't noticed that problem, but I have noticed that the search works better for subjects than words in the body of the messages.
