Find and replace whole words in vim

Question

To find and replace all instances of a word in vim, I use

%s/word/newword/g

How do I change this so that it only finds instances of \"word\

Answer 1

For case-sensitive replace.. you can use "\C"

:%s/\\C/newword/g

It replaces only "word" with newword leaving others like Word,WORD... unreplaced.
