免费chatgpt使用网址 http://ffff.chat:2023  在设置中设置userID

 

 

1. 新建一个索引,索引名为account

PUT account
{
  
}

2. 创建索引映射文件

其中text类型,es会自动分词,另外添加一个属性字段keyword,保存原来不分词的字段

PUT account/_mapping
{
  "properties": {
    "account_name": {
      "type": "text",
      "analyzer": "ik_smart",
      "fields": 
      { 
        "keyword": 
{ "type": "keyword", "ignore_above": 256 } } } } }

3. 添加一条记录doc,并且设置id

PUT account/_doc/1
{
  "account_name": "程序员的早餐"
}
PUT account/_doc/4
{
  "account_name": "早餐的程序员"
}

4. 查询记录

GET account/_search
{
  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "account_name.keyword": "早餐的程序员"
          }
        },
        {
          "match": {
            "account_name": "早餐的程序员"
          }
        }
      ]
    }
  }
}

 5  多个字段匹配查询

GET question/_search
{
  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "title": "杭州"
          }
        },
        {
          "match": {
            "content": "杭州"
          }
        }
      ]
    }
  }
}

 

  6 提高权重

 

GET question/_search
{
  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "title": {
               "query": "北京",
               "boost": 2
            }
          }
        },
        {
          "match": {
            "content": {
               "query": "北京",
               "boost": 1
            }
          }
        }
      ]
    }
  }
}
