6.2.2版本的同义词加上去后高亮有混乱

同义词是这样的：英文绘本,原版绘本,英语绘本,英文图画书

我搜索英文绘本，结果高亮是这样的：２－８岁英文原版绘本大推荐
高亮的内容为：英文原版绘本 推荐

索引的配置是这样的：

PUT _template/template_default

{

  "index_patterns": ["*"],

  "order" : 0,

  "settings": {

    "index": {

      "analysis": {

        "analyzer": {

          "ik_syno": {

            "filter": ["my_synonym_filter"],

            "tokenizer": "ik_max_word",

            "type": "custom"

          },

          "ik_syno_smart": {

            "filter": ["my_synonym_filter"],

            "tokenizer": "ik_smart",

            "type": "custom"

          }

        },

        "filter": {

          "my_synonym_filter": {

            "synonyms_path": "synonyms.txt",

            "type": "synonym"

          }

        }

      }

    }

  }

}

分词测试是这样的：

POST /viw_experience/_analyze

{

  "analyzer": "ik_syno",

  "text": "2-8岁英文原版绘本大推荐"

}

分词结果：

      "position": 6

    },

    {

      "token": "英语",

      "start_offset": 6,

      "end_offset": 8,

      "type": "SYNONYM",

      "position": 6

    },

    {

      "token": "图画书",

      "start_offset": 6,

      "end_offset": 8,

    },

    {

      "token": "绘本",

      "start_offset": 8,

      "end_offset": 10,

      "type": "CN_WORD",

      "position": 7

    },

    {

      "token": "英文",

      "start_offset": 8,

      "end_offset": 10,

      "type": "SYNONYM",

      "position": 7

    },

    {

      "token": "绘本",

      "start_offset": 8,

      "end_offset": 10,

      "type": "SYNONYM",

      "position": 7

    },

    {

      "token": "图画",

      "start_offset": 8,

      "end_offset": 10,

      "type": "SYNONYM",

      "position": 7

    },

    {

      "token": "推荐",

      "start_offset": 11,

      "end_offset": 13,

      "type": "CN_WORD",

      "position": 8

    },

    {

      "token": "绘本",

      "start_offset": 11,

      "end_offset": 13,

      "type": "SYNONYM",

      "position": 8

    }

  ]

}

最后的这个分词是不对的：

    {

      "token": "绘本",

      "start_offset": 11,

      "end_offset": 13,

      "type": "SYNONYM",

      "position": 8

    }
