Custom analyzer with large char_filter list creation for elasticsearch
<p>I try to add custom analyzer to elastic search. I got a too large "mappings" list of synonyms (mapper_list). Size of mapper_list is about 30.000 elements.</p>

<pre><code>requests.post(es_host + '/_close')

settings = {
    "settings" : {
        "analysis" : {
            "char_filter" : {
                "my_mapping" : {
                    "type" : "mapping",
                    "mappings" : mapper_list
                }
            },
            "analyzer" : {
                "my_analyzer" : {
                    "tokenizer" : "standard",
                    "char_filter" : ["my_mapping"]
                }
            }
        }
    }
}

requests.put(es_host + '/_settings',
             data=json.dumps(settings))

requests.post(es_host + '/_open')
