title: Regular expression search or LIKE type feature in cassandra
body: <p>I am using datastax cassandra ver 2.0.
  How do we search in cassandra column a value using regular expression.Is there way to achieve 'LIKE' ( as in sQL) functionality ?</p>
  
  <p>I have created table with below schema.</p>
  
  <pre><code>CREATE TABLE Mapping (
  id timeuuid,
  userid text,
  createdDate timestamp,
  createdBy text,
  lastUpdateDate timestamp,
  lastUpdateBy text,
  PRIMARY KEY (id,userid)
  );
  </code></pre>
  
  <p>I inserted few test records as below.</p>
  
  <pre><code>       id                                  | userid   | createdby
       -------------------------------------+----------+-----------
        30c78710-c00c-11e3-bb06-1553ee5e40dd |      Jon |     admin
        3e673aa0-c00c-11e3-bb06-1553ee5e40dd |     Jony |     admin
        441c4210-c00c-11e3-bb06-1553ee5e40dd | Jonathan |     admin
  </code></pre>
  
  <p>I need to search records, where userid contains the word 'jon'.So that in results, i get all records, containing jon,jony,jonathan.</p>
  
  <p>I know,there is no sql LIKE functionality in cassandra.
  But is there any way to achieve it in cassandra ?
  (NOTE: I am using datastax-java driver as client api).</p>
