No, it doesn't look like that is supported. You can search for strings, and get the index (in the whole character array) but it doesn't really help. Since you don't know what line it's on. Also, the scroll to line function only works on actual lines (after a line break) not on auto-wrapped text, which makes it even more difficult. I tried to get a rough idea where the text is (you can sort of get a percentage based on the substring index and the total character count) but this is unreliable.
