Question

我已将1000张汽车记录批量放入ElasticSearch。

{ "index" : { "_index" : "car", "_type" : "car", "_id" : "1" } }
{"id":1,"car_make":"Chevrolet","car_model":"Express","car_year":2012,"car_color":"Goldenrod","made_in":"Indonesia"}
{ "index" : { "_index" : "car", "_type" : "car", "_id" : "2" } }
{"id":2,"car_make":"BMW","car_model":"Z8","car_year":2002,"car_color":"Fuscia","made_in":"China"}
{ "index" : { "_index" : "car", "_type" : "car", "_id" : "3" } }
...
...
...

当我运行以下内容时，我希望得到一些结果，但现在我的结果为零。

Answer 1

您是否为car（索引/类型）创建了自定义映射？如果没有，它将默认为text keyword字段类型（如果您使用es 5.x无法记住确切版本）。

如果是这种情况，你可以尝试：

{
  "query": {
    "bool": {
      "filter": {
        "terms": {
          "car_make.keyword": ["BMW","Lexus"]
        }
      }
    }
  }
}

ElasticSearch - 搜索过滤器不起作用
