Adding ngram to existing index
<p>Is there a way to add ngram matching to existing index? I saw plenty examples in documentation how to create index which will search through using ngrams, but when I try to follow those instructions I get error:</p>

<pre><code>{"error":"IndexAlreadyExistsException[[nameOfIndex] already exists]","status":400}
</code></pre>

<p>Example curl which I'm using:</p>

<pre><code>curl -XPUT elasticUrl/nameOfIndex -d '{
   "settings": {
      "number_of_shards": 1
   },
   "mappings": {
      "title": {
         "properties": {
            "text_field": {
               "type": "string",
               "term_vector": "yes"
            }
         }
      }
   }
}'
</code></pre>
