Hi Alexander, thanks for your swift reply. I am new to Regex and wrote the below line, but it doesn't get what I know. Basically, what I want is, to find word A (which starts with the word "go", e.g. go, goes, going) and word B (which starts with the word "up", e.g. up, upon, upward), and they are near each other (i.e. a space, or at most 5 any other words). Appreciate your advice.
