ES对搜索结果处理

1、排序

#sort排序
GET /hotel/_search
{
  "query": {
    "match_all": {}
  },
  "sort": [
    {
      "score": "desc"
    },
    {
      "price": "asc"
    }
  ]
}

#找到121.6，31周围的酒店，距离升序排序
GET /hotel/_search
{
  "query": {
    "match_all": {}
  },
  "sort": [
    {
    "_geo_distance": {
      "location": {
        "lat": 31,
        "lon": 121.6
      },
      "order": "asc",
       "unit": "km"
    }
    }
  ]
}

2、分页

# 分页查询
GET /hotel/_search
{
  "query": {
    "match_all": {}
  },
  "sort": [
    {
      "price":"asc"
    }
  ],
  "from": 0,  #分页开始的位置，默认为0
  "size": 20  #期望获取的文档总数
}

3、高亮

#高亮查询,默认情况下，ES搜索字段必须与高亮字段一致，需要修改配置require_field_match
GET /hotel/_search
{
  "query": {
    "match": {
      "all": "如家"
    }
  },
  "highlight": {
    "fields": {
      "name": {
        "require_field_match": "false"
      }
    }
  }
}
