首先安装插件 dynamic-synonym，

        "analysis": {
            "analyzer":{
                    "mysynonym":{
                        "type": "custom",
                        "tokenizer":"ik_max_word",
                        "filter":[
                            "remote_synonym"
                        ]
                    }
                },
                "filter":{
                    "remote_synonym":{
                        "expand": true,
                        "ignore_case": true,
                        "type": "dynamic_synonym",
                        "synonyms_path" :  "http://*/word/getAllSynonymToTokenStream",
                        "interval": 60
                    }
