title: Regular Expression for Full Name(must be two words or more)
body: <p>I have tried to define a regular expression for the full name of person, in the form: "Deepak Das" or "Deepak Bidyabhusan Das". The name must contain at least two words like the the ones above, and it must not permit single word name like "Deepak" or "Roger" etc. I have tried a lot, but none of the expressions seem to be working.</p>
  
  <p>These are the expressions I have tried so far:</p>
  
  <pre><code>^[a-z A-Z]+$---&gt; this one is allowing any word names  
  ^[a-zA-Z\s]+$  
  ^[a-zA-Z\\s]+$  
  ^[a-z A-Zs]+$,  
  ^([a-zA-Z]\s[a-zA-Z])+$ ---&gt; this one is allowing only three word or more.
  </code></pre>
  
  <p>Could you please explain what I may have done wrong and how I can fix it?</p>
