1. 自定义分词器

ES如何支持拼音和中文分词 ？
自定义分词器 支持拼音和中文分词

PUT /jd_goods
{
   "settings": {
        "analysis": {
            "analyzer": {
                "ik_smart_pinyin": {
                    "type": "custom",
                    "tokenizer": "ik_smart",
                    "filter": ["my_pinyin", "word_delimiter"]
                },
                "ik_max_word_pinyin": {
                    "type": "custom",
                    "tokenizer": "ik_max_word",
                    "filter": ["my_pinyin", "word_delimiter"]
                }
            },
            "filter": {
                "my_pinyin": {
                    "type" : "pinyin",
                    "keep_separate_first_letter" : true,
                    "keep_full_pinyin" : true,
                    "keep_original" : true,
                    "limit_first_letter_length" : 16,
                    "lowercase" : true,
                    "remove_duplicated_term" : true
                }
            }
        }
  }
}

2. 映射模型

重新指定文档类型映射拼音分词类型

POST /jd_goods/_mapping
{
        "properties": {
            "title": {
                "type": "text",
                "analyzer": "ik_max_word_pinyin",
                "search_analyzer": "ik_smart_pinyin"
            },
            "desc": {
                "type": "text",
               "analyzer": "ik_max_word_pinyin",
               "search_analyzer": "ik_smart_pinyin"
            },
            "img": {
                "type": "text"
            },
            "price": {
                "type": "text"
            }
        }
}

1.和2.可以合并为下面这一条命令

PUT /jd_goods
{
   "settings": {
        "analysis": {
            "analyzer": {
                "ik_smart_pinyin": {
                    "type": "custom",
                    "tokenizer": "ik_smart",
                    "filter": ["my_pinyin", "word_delimiter"]
                },
                "ik_max_word_pinyin": {
                    "type": "custom",
                    "tokenizer": "ik_max_word",
                    "filter": ["my_pinyin", "word_delimiter"]
                }
            },
            "filter": {
                "my_pinyin": {
                    "type" : "pinyin",
                    "keep_separate_first_letter" : true,
                    "keep_full_pinyin" : true,
                    "keep_original" : true,
                    "limit_first_letter_length" : 16,
                    "lowercase" : true,
                    "remove_duplicated_term" : true
                }
            }
        }
  },
    "mappings": {
        "properties": {
            "title": {
                "type": "text",
                "analyzer": "ik_max_word_pinyin",
                "search_analyzer": "ik_smart_pinyin"
            },
            "desc": {
                "type": "text",
               "analyzer": "ik_max_word_pinyin",
               "search_analyzer": "ik_smart_pinyin"
            },
            "img": {
                "type": "text"
            },
            "price": {
                "type": "text"
            }
        }
    }
}
