title: Using Custom ElasticSearch Analyzer
body: <p>I have a question regarding elastic search analyzers.
  I create a custom analyzer like this:</p>
  
  <pre><code>Analyzers(o =&gt; o.Custom("custom", 
                          m =&gt; m.CharFilters("icu_normalizer").Filters("lowercase", "asciifolding").Tokenizer("icu_tokenizer")
  </code></pre>
  
  <p>And tried the analyzer which results in the following token (good):</p>
  
  <pre><code>/_analyze?analyzer=custom&amp;text=SödertorG
  
  {
      "tokens": [
          {
              "token": "sodertorg",
              "start_offset": 0,
              "end_offset": 9,
              "type": "&lt;ALPHANUM&gt;",
              "position": 0
          }
      ]
  }
  </code></pre>
  
  <p>But when I try to search for this token, like this:</p>
  
  <pre><code>_search?q=sodertorg&amp;analyzer=custom
  </code></pre>
  
  <p>I don't get any results (bad).</p>
  
  <pre><code>{
      "took": 1,
      "timed_out": false,
      "_shards": {
          "total": 5,
          "successful": 5,
          "failed": 0
      },
      "hits": {
          "total": 0,
          "max_score": null,
          "hits": []
      }
  }
  </code></pre>
  
  <p>Am I missing something?
  Thanks.</p>
