ik分词器使用

  1. 创建索引

    curl -XPUT http://localhost:9200/index

  2. 设置mapping

    curl -XPOST http://localhost:9200/index/fulltext/_mapping -d'
    {
        "fulltext": {
                 "_all": {
                "analyzer": "ik_max_word",
                "search_analyzer": "ik_max_word",
                "term_vector": "no",
                "store": "false"
            },
            "properties": {
                "content": {
                    "type": "string",
                    "analyzer": "ik_max_word",
                    "search_analyzer": "ik_max_word",
                    "include_in_all": "true",
                    "boost": 8
                }
            }
        }
    }'

    url中fulltext和json内容的fulltext这2处名称要一直，否则创建mapping报错

    ik分词是否生效

    浏览器直接访问

    http://localhost:9200/_analyze?analyzer=ik&pretty=true&text=我是中国人

    或者

    6
    curl -XGET localhost:9200/_analyze -d'
    {
      "analyzer": "ik",
      "text": "我是中国人"
    }
    '

    ik没生效和话，elasticsearch中文默认(把analyzer=ik去掉)是一个字一个字进行分词。

    ps:上面集群搭建直接使用elasticsearch官方镜像也可以，本镜像只是添加了ik中文分词器
