二、题目

对 task 索引中文档的 fielda， fieldb， fieldc 字段进行查询，并
要求最终的算分是fielda， fieldb， fieldc 字段上算分的总和，同时要求对 fieldb 字段设置 boosting 值

# 创建符合条件的 task 索引，设置 field 字段，并写入数据
PUT task
{
  "mappings": {
    "properties": {
      "fielda":{
        "type": "text"
      },
      "fieldb":{
        "type": "text"
      },
      "fieldc":{
        "type": "text"
      },
      "fieldd":{
        "type": "long"
      }
    }
  }
}

# 写入数据
POST task/_bulk
{"index":{}}
{"fielda":"中国人民广场", "fieldb":"天安门", "fieldc":"中国人民广场", "fieldd": 5}
{"index":{}}
{"fielda":"中华人民共和国万岁", "fieldb":"日月潭", "fieldc":"中国人民广场", "fieldd": 6}
{"index":{}}
{"fielda":"山上山下红旗飘飘", "fieldb":"农民翻身把歌唱", "fieldc":"中国人民广场", "fieldd": 4}
{"index":{}}
{"fielda":"中国共产党万岁", "fieldb":"中国人民广场", "fieldc":"中国人民广场", "fieldd": 5}
{"index":{}}
{"fielda":"春眠不觉晓", "fieldb":"中国人民", "fieldc":"处处闻啼鸟", "fieldd": 5}

2.1 考点

1. Multi-match

2.2 答案

GET task/_search
{
  "query": {
    "multi_match" : {
      "query" : "中华人民",
      "fields" : [ "fielda", "fieldb^2", "fieldc"] 
    }
  }
}

这里更新一个 分数的计算方式

GET task/_search
{
  "query": {
    "multi_match" : {
      "query" : "中华人民",
      "fields" : [ "fielda", "fieldb^2", "fieldc"],
      "type": "most_fields"
    }
  }
}
