title: meteor if document exists return true/false
body: <p>How can I determine if a document exists within a collection in Meteor?  </p>
  
  <p>Edited:  New code.</p>
  
  <p>the mongodb has a document with the ProductName: Apples
  the inputproduct is "Apples"</p>
  
  <pre><code>var exists = Products.find({ProductName: inputproduct});
                      if(exists)
                      {
                          alert("it exists");
                      }else{
                          alert('doesnt exist');
                      }
  </code></pre>
  
  <p>all I get back is : "it exists" regardless of the value of inputproduct.  I have output what inputproduct is and it comes back "Apples" no problem.  Not sure what is going on here.  Tried it several ways using find or findOne and nothing.</p>
