如何在Elasticsearch中按數組字段搜索？

Question

我已經索引了這樣的文檔：

[PUT] /my_index/cars/1

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

我正在嘗試搜索“約翰”是乘客的所有汽車。

Answer 1

您可以像搜索其他任何字段一樣進行搜索。

-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" ]
      }
    } ]
  }
}

Answer 2

盡管codegrep_admin的答案有效，但我一直在尋找可以更輕松地操作的東西。

我最終使用了bool查詢，如下所示：

[GET] /my_index/cars/_search

{
    "query": {
    "bool": {
        "must": [
            { "match": { "passengers": "John" }},
            { "match": { "passengers": "Annie" }}
      ]
    }
}
