title: Query Influxdb based on tags?
body: <p>I have started playing around with Influxdb v0.13 and I have some dummy values in my test db where <code>id</code> is a tag and <code>value</code> is a field:</p>
  
  <pre><code>&gt; SELECT * FROM dummy
  name: dummy
  --------------
  time                    id     value
  1468276508161069051     1234    12345
  1468276539152853428     613     352
  1468276543470535110     613     4899
  1468276553853436191     1234    12
  </code></pre>
  
  <p>I get no results returned when I run this query:</p>
  
  <pre><code>&gt; SELECT * FROM dummy WHERE id=1234
  </code></pre>
  
  <p>but I do get the following when querying with the field instead:</p>
  
  <pre><code>&gt; SELECT * FROM dummy WHERE value=12
  name: dummy
  --------------
  time                    id     value
  1468276553853436191     1234    12
  </code></pre>
  
  <p>Am I doing something wrong here? I thought the point of tags were to be queried (since they are indexed and fields are not), but they seem to break my queries.</p>
