1.原理

1. 使用copy_to将需要查询的参数值复制到一个属性中
2. 使用wildcard关键词进行查询

2.实现

1. 创建索引，将所有string类型的数据复制到cmp_full_name中

   PUT /cmdb/
   {
     "mappings" : {
           "dynamic_templates" : [
           {
             "copy_to_full":{
               "mapping": {
                 "copy_to": "cmp_full_name"
               },
               "match_mapping_type": "string",
               "unmatch":"cmp_full_name"
             }
           },
           {
             "message_field" : {
               "path_match" : "message",
               "match_mapping_type" : "string",
               "mapping" : {
                 "norms" : false,
                 "type" : "text"
               }
             }
           },
           {
             "string_fields" : {
               "match" : "*",
               "match_mapping_type" : "string",
               "mapping" : {
                 "analyzer" : "simple",
                 "norms" : false,
                 "type" : "text"
               }
             }
           }
         ],
         "properties": {
           "cmp_full_name":{
             "type": "keyword"
           }
         }
       }
   }
   

2. 代码关键实现

     String key = "*" + cmdbGlobalSearchQueryVo.getKeyword() + "*";
               BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
               WildcardQueryBuilder wildcardQueryBuilder = QueryBuilders.wildcardQuery("cmp_full_name", key);
               boolQueryBuilder.should(wildcardQueryBuilder);
