title: Behavior of elasticsearch-analysis-kuromoji is not what i expected
body: <p>I have been using elasticsearch-analysis-kuromoji to perform searches in Japanese, but I have been getting two very strange behaviours, the first one being that the characters I search for will not work, like - '輸出貿易' will not work unless I pass it as '輸 出 貿 易' with spaces between each character. 
  Also characters like ント are not searched on.</p>
  
  <p>This is my configuration:</p>
  
  <pre><code>            .setSettings(ImmutableSettings.settingsBuilder().loadFromSource(jsonBuilder()
                      .startObject()
                      .startObject("analysis")
                              //
                      .startObject("tokenizer")
                      .startObject("kuromoji_user_dict")
                      .field("type", "kuromoji_tokenizer")
                      .field("mode", "extended")
                      .field("discard_punctuation", "false")
                      .endObject()
                      .endObject()
                              //
                      .startObject("analyzer")
                      .startObject(JAPANESE_LANGUAGE_ANALYSIS)
                      .field("type", "custom")
                      .field("tokenizer", "kuromoji_user_dict")
                      .endObject()
                      .endObject()
                              //
  
                      .endObject()
                      .endObject().string()));
  </code></pre>
  
  <p>Am I configuring it wrong or do I need a different tokeniser for character like:
  '輸出貿易 and ント' </p>
  
  <p>Thank You</p>
