1.elasticsearch中的搜索结果处理

案例1

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

案例2

DSL
# 31.034661 121.612282
GET /hotel/_search
{
  "query":{
    "match_all": {}
  },
  "sort":[
    {
      "_geo_distance": {
        "location": {
          "lat": 31.034661,
          "lon": 121.612282
        },
        "order": "asc",
        "unit": "km"
      }
    }]
}

2.分页结果

示例

DSL
GET /hotel/_search
{
  "query":{
    "match_all": {}
  },
  "sort":[
    {
      "price":"asc"
    }
    ],
    "from": 0,
    "size": 20
}

深度分页问题

解决方案

3.结果高亮显示

DSL
GET /hotel/_search
{
  "query":{
    "match": {
      "all": "如家"
    }
  },
  "highlight": {
    "fields": {
      "name": {
        "require_field_match": "false"
      }
    }
  }
}

4.使用RestClient实现es查询
