: 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).
