title: how to retrive objects in bucket with 'suffix'
body: <p>I am using Ruby SDK for AWS:S3. I have files  listed in bucket like below:</p>
  
  <pre><code>s3://client1/client_name_delivery1_2013-05-01.txt
  s3://client1/client_name_delivery2_2013-05-01.txt
  </code></pre>
  
  <p>There may be many files for particular date. I want to fetch all the files for particular date e.g. for <code>2013-05-01</code>. I found prefix option of <code>objects method</code> of bucket however did not find something like suffix </p>
  
  <p>How should I fetch files by suffix?</p>
