使用 ruby​​ gem 的 elasticsearch 嵌套查询

Question

我正在使用 elasticsearch ruby​​ gem 连接到一个 es 服务器，并且目前有一个具有以下映射的索引。我试图了解查询这些嵌套对象的正确语法。尝试如下查询，但不断出错。我想知道是否有人可以让我开始使用正确的语法来查询这样的结构？谢谢！

client = Elasticsearch::Client.new log:true

client.search index: 'injuries', nested: { path: { week: {id: '1' } } }

返回：

Elasticsearch::Transport::Transport::Errors::BadRequest: [400] {"error":"SearchPhaseExecutionException[Failed to execute phase [query

示例映射：

    "mappings" : {
      "tbd" : {

          "injuries" : {

您的nested query 似乎没有定义query。我认为应该是这样的：

"nested" : {
    "path" : "week",
    "query" : {
        "match" : {"week.id" : "1"}
     }
}
