elasticsearch - 如何在Elasticsearch中按数组字段搜索？

Question

我已经索引了这样的文档:

[PUT] /my_index/cars/1

{
    "color" : "red",
    "passengers" : ["John", "Annie", "William"]
}

我正在尝试搜索“约翰”是乘客的所有汽车。

Answer 1

您可以像搜索其他任何字段一样进行搜索。

-bash-4.2$ curl 'localhost:9200/my_index/_search?pretty=true&q=passengers:John'
{
  "took" : 4,
  "timed_out" : false,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
    "failed" : 0
  },
  "hits" : {
    "total" : 1,
    "max_score" : 0.15342641,
    "hits" : [ {
      "_index" : "my_index",
      "_type" : "cars",
      "_id" : "1",
      "_score" : 0.15342641,
      "_source" : {
        "color" : "red",
        "passengers" : [ "John", "Annie", "William" ]
      }
    } ]
  }
}
