Type : before searching: :/someStringtoFind Enter. If the match isn't at the beginning of the line, press n to go to the beginning of the match.
/someStringtoFind/ is an empty ex command with the range of lines /someStringtoFind/ (a 1-line range). The empty ex command means “jump to the end of the range”, so the command jumps to the next line containing a match for someStringtoFind. You can drop the final / if you have nothing to put afterwards.
:/someStringtoFind drops you to the beginning of the target line. The search is stored in the search history, so n brings you to the beginning of the next match, which is on the current line. There's an exception: if the match starts at the beginning of the line, then you're already at the beginning of the match, and n would bring you to the next match. As long as the match doesn't span lines, $N brings you to the beginning of the match reliably, if you don't mind the extra typing (or are writing a macro).
