title: How to look for exact matching word using Golang regexp?
body: <p>I am trying to find words in a large text file. The <code>MatchString</code> method doesn't inherently look for exact word match, rather it looks for the pattern as it should.</p>
  
  <p>How does one check for exact word match using regexp package in Golang? I have tried some regex'es i found on SO, but it didn't work.</p>
