elasticsearch5.x Settings设置Jcseg+Lc Pinyin组合分析器,求助大神

进行如下配置：
{
  "settings": {
    "analysis": {
      "analyzer": {
        "jcseg": {
          "alias": "jcseg_analyzer",
          "type": "org.lionsoul.jcseg.elasticsearch.index.analysis.JcsegAnalyzerProvider"
        },
        "jcseg_complex": {
          "type": "custom",
          "tokenizer": [
            "jcseg_complex"
          ],
          "filter": [
            "lc_first_letter"
          ]
        }
      },
      "tokenizer": {
        "jcseg_complex": {
          "type": "jcseg",
          "seg_mode": "complex"
        }
      }
    }
  }
}

报错是Jcseg未知的Tokenizer, 
 {"error": {

"root_cause": [

{

"type": "illegal_argument_exception",
"reason": "Unknown tokenizer type [jcseg] for [jcseg_complex]"

}

],
"type": "illegal_argument_exception",
"reason": "Unknown tokenizer type [jcseg] for [jcseg_complex]"

},
"status": 400}
