title: Finding exact match in vim
body: <p>Using <code>/</code> or <code>?</code> enables to find a match for a word in vim. But how can I find an exact match?
  For example, my text contains the following words: <code>a aa aaa aaaa aa</code> and I type <code>/aa</code> This will find all the strings containing the pattern aa, but what if I want to find exactly <code>aa</code> and not <code>aaaa aaaa</code>?</p>
