es索引添加自定义数字分词器

1、创建索引、分片、副本

PUT /waybill_test
{
    "index": {
        "number_of_replicas" : 1,         
        "number_of_shards" : 3
    }
}

2、关闭索引

POST waybill_test/_close

3、添加自定义分词器、在添加自定义分词器之前需要关闭索引

PUT waybill_test/_settings
{
  "settings": {
        "analysis": {
              "analyzer": {
                  "search_ngram_analyzer": {             
                      "tokenizer": "my_ik_tokenizer", 
                      "filter": "ik_first_letter_and_full_ngram_filter" 
                  },
                  "ngram_analyzer": {             
                      "tokenizer": "ngram_tokenizer" 
                  }
              },
              "tokenizer": {
                  "my_ik_tokenizer": {             
                      "type": "ik_smart"
                  },
                  "ngram_tokenizer": {
                      "type": "ngram",
                      "min_gram": 1,
                      "max_gram": 6,
                      "token_chars": [
                          "letter",
                          "digit"
                      ]
                  }
              },
              "filter": {
                  "ik_first_letter_and_full_ngram_filter": {
                      "type": "ngram",
                      "min_gram": 1,
                      "max_gram": 6,
                      "token_chars": [
                          "letter",
                          "digit"
                      ]
                  }
              }
       }
  }
}

4、打开索引

POST waybill_test/_open

5、添加properties字段及 analyer分词器

PUT /waybill_test/waybill_test_type/_mappings
{
  "properties": {
    "search_remark": {
       "type": "text",
       "analyzer": "search_ngram_analyzer"
     }
   }
}
