title: Case insensitivity does not work
body: <p>I cant figure out why my searches are case sensitive.  Everything I've read says that ES is insensitive by default.  I have mappings that specify the standard analyzer for indexing and search but it seems like some things are still case sensitive - ie, wildcard:</p>
  
  <pre><code>"query": {
  "bool": {
    "must": [
      {
        "wildcard": {
          "name": {
            "value": "Rae*"
          }
        }
      }
    ]
  }
  </code></pre>
  
  <p>This fails but "rae*" works as wanted.  I need to use wildcard for 'starts-with' type searches (I presume).</p>
  
  <p>I'm using NEST from a .Net app and am specifying the analyzers when I create the index thus:</p>
  
  <pre><code>  var settings = new IndexSettings();
    settings.NumberOfReplicas = _configuration.Replicas;
    settings.NumberOfShards = _configuration.Shards;
    settings.Add("index.refresh_interval", "10s");
    settings.Analysis.Analyzers.Add(new KeyValuePair&lt;string, AnalyzerBase&gt;("keyword", new KeywordAnalyzer()));
    settings.Analysis.Analyzers.Add(new KeyValuePair&lt;string, AnalyzerBase&gt;("simple", new SimpleAnalyzer()));
  </code></pre>
  
  <p>In this case it's using the simple analyzer but the standard one has the same result.</p>
  
  <p>The mapping looks like this:</p>
  
  <pre><code>name: {
      type: string
      analyzer: simple
      store: yes
  }
  </code></pre>
  
  <p>Anyone got any ideas whats wrong here?</p>
  
  <p>Thanks</p>
