title: Rails find by part of string
body: <p>I want to do a find in Rails basically to check if an object already exists in the database.
  I have a CSV, which I have little control over the format of it.
  I have a field in the CSV called 'name' which is the example I have contains 5 words. This field contains a name and address, but it is not confined to any format.</p>
  
  <p>In my database I have fields such as 'name', 'address 1', 'address 2'.
  Basically I want to see if any part of the name field in the CSV matches up to any of the fields in my database.</p>
  
  <p>I know I have to do a SQL like command probably but am not sure how to go about it. </p>
