title: How to search with keyword analyzer?
body: <p>I have keyword analyzer as default analyzer, like so:</p>
  
  <pre><code>{
    "settings": {
      "index": {
        "analysis": {
          "analyzer": {
            "default": {
              "type": "keyword"
  }}}}}}
  </code></pre>
  
  <p>```</p>
  
  <p>But now I can't search anything. e.g:</p>
  
  <pre><code>{
    "query": {
      "query_string": {
        "query": "cast"
  }}}
  </code></pre>
  
  <p>Gives me 0 results all though "cast" is a common value i the indexed documents. (<a href="http://gist.github.com/baelter/b0720a52ee5a27e27d3a" rel="nofollow">http://gist.github.com/baelter/b0720a52ee5a27e27d3a</a>)</p>
  
  <p>Search for "*" works fine btw.</p>
  
  <p>I only have explicit defaults in my mapping:</p>
  
  <pre><code>{
    "oceanography_point": {
      "_all" : {
        "enabled" : true
      },
      "properties" : {}
   }
  }
  </code></pre>
  
  <p>The index behaves as if no fields are included in _all, because field:value queries works fine.</p>
  
  <p>Am I misusing the keyword analyzer?</p>
