title: How to search secondary index in Cassandra without equality?
body: <p>I need to be able to perform search on secondary indexes using only &lt;, >, &lt;=, or >=. I understand that Cassandra requires at least one equality index clause because it iterates over all the results from that equality index.</p>
  
  <p>Are there any tricks to perform operations using only &lt;, >, &lt;=, or >= (at least conceptually)? Is it a bad idea?</p>
  
  <p>Also, does anybody know if there are any plans to change this in Cassandra?</p>
  
  <p>Thanks!</p>
