Root mapping definition has unsupported parameters

ES 2.2.0

I get this error:

# curl -XPUT http://localhost:9200/vendnext_new_no_auth_index/ -d @./vendnext_new_no_auth_index.config.json
{"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"Root mapping definition has unsupported parameters:  [search_analyzer : search_ngram] [index_analyzer : index_ngram]"}],"type":"mapper_parsing_exception","reason":"Failed to parse mapping [vendnext_new_no_auth_type]: Root mapping definition has unsupported parameters:  [search_analyzer : search_ngram] [index_analyzer : index_ngram]","caused_by":{"type":"mapper_parsing_exception","reason":"Root mapping definition has unsupported parameters:  [search_analyzer : search_ngram] [index_analyzer : index_ngram]"}},"status":400}

With this schema:

  "mappings": {
    "vendnext_new_no_auth_type":{

    }

        }
      }
    }
  }
}

Any way to avoid this? Thanks.
