elasticsearch5.0集成ik分词问题(type报错)

es版本：5.0.2，我下载了[url=https://github.com/medcl/elasticsearch-analysis-ik]https://github.com/medcl/elasticsearch-analysis-ik[/url] 然后因为应用场景的需要，我修改了ik分词源码，增加了一些参数，我需要在es中配置几个analyzer，因为现在不能直接在yml配置了，所以使用了indices template，对应配置如下：

{

	"template" : ["*"],

	"order" : 0,

	"settings" : {

		"analysis" : {

			"analyzer" : {

				"ik" : {

					"alias" : ["ik_analyzer"],

					"type" : "org.elasticsearch.plugin.analysis.ik.AnalysisIkPlugin",

					"use_smart" : "false",

					"cut_formula" : "true"

				},

				"ik_max_word" : {

					"type" : "ik",

					"use_smart" : "false",

					"cut_formula" : "true"

				},

				"ik_smart" : {

					"type" : "ik",

					"use_smart" : "true",

					"cut_formula" : "false"

				},

				"ik_smart_cut_formula" : {

					"type" : "ik",

					"use_smart" : "true",

					"cut_formula" : "true"

				},

				"ik_not_cut_formula" : {

					"type" : "ik",

					"use_smart" : "false",

					"cut_formula" : "false"

				}

			}

		}

	}

}

会报错Unknown analyzer type [org.elasticsearch.plugin.analysis.ik.AnalysisIkPlugin] for [ik]。其中，cut_formula就是我新添加的控制分词的参数。求大神们帮忙分析一下，有原理更好了。谢谢！！！
