backspace in vi search

Hi gurus, i use vi editor. when I want search something I Type / (or ? if i want search backward), that is OK.
But when i make mistake in searching string how can i delete character ?

I tried bacskpase but did not work (gives just strange characters).
Also tried shift+bacskspace but this only shift cursor left and I am able ONLY to REPLACE character (so there is problem if misspelled word is longer that wanted word)

Thanks a lot.

It will work. (its working me fine)
Have you set anything in your .vimrc file?

move your .vimrc file to some other name then check it

I will check it and let you know (because it is computer at work), on my home machine it also works :), it must be either .vimrc or fact that computer at work is running solaris

Can you tell me the terminal settings of the systems affected? Just run "echo $TERM" on the shell on this system.
