过滤器

​​filter​​ 可以使用它进行数据过滤

• ge 大于
• gte 大于等于
• lt 小于
• lte 小于等于

GET quanzhan/user/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "name": "王"
          }
        }
      ],
      "filter": {
        "range": {
          "age": {
            "gte": 10,
            "lte": 20

精确查询

​​term​​ 查询是直接通过倒排索引指定的词条进行精确查找

关于分词

• ​​term​​ 直接查询精确的
• ​​match​​ 会使用分词解析器(先分析文档, 然后通过分析文档进行查询)

两个类型 text keyword

创建索引

PUT testdb
{
  "mappings": {
    "properties": {
          "name":{
      "type":"text"
    },
    "desc": {
      "type": "keyword"
    }
    }
  }
}

反馈结果

{
  "acknowledged" : true,
  "shards_acknowledged" : true,
  "index" : "testdb"
}

插入数据

PUT testdb/_doc/1
{
  "name": "全栈自学社区",

}


PUT testdb/_doc/2
{

总结

这些其实 MySql也可以做, 效率低

• 匹配
• 按照条件匹配
• 精确匹配
• 区间范围匹配
• 匹配字段过滤
• 多条件查询
• 高亮查询
