title: Where is the reference documentation on the Kibana query language?
body: <p>I have been searching on google for this multiple times and always give up.  Here is the best thing I've been able to find on the topic: <a href="https://www.elastic.co/guide/en/kibana/3.0/queries.html" rel="nofollow">https://www.elastic.co/guide/en/kibana/3.0/queries.html</a></p>
  
  <p>This is lacking.  For example, how do I search for strings that "start with" a string. Or, "end width"?  Or how do I use a regex?  etc.  I don't want these questions directly answered, I just want a link to the documentation that answers these things. </p>
  
  <p>I am using Kibana 4.</p>
