title: Finding common partial strings between 2 datasets in R
body: <p>I have two datasets - One with a list of 1 million companies, another with 15,000. I need to find companies common to both of these.
  The problem is that the names are not exactly same, thus I need to do partial matching.
  For example: In database 1: ABC Industries, In database 2: ABC. Can I match these two rows using R?</p>
  
  <p>P.S. - I am a beginner to R but willing to learn quickly.</p>
