as per Isthirirel:

"The Quick-Search bar is kind of nice, but it is really only jumping to the stub you type (same as in Windows Explorer when you have a file-list open). I'd like something closer to web-browser quick search, where you can type /pla and you are at the first Plains entry and a couple of seconds later it forgets you've typed anything so typing /mou takes you to the first Mountain entry. Too often I type plamou in the Quick-Search box which takes me to the last Plains entry"

Surely, this should be configurable and non-default behavior if it gets implemented.
