Question

我在我的Django项目中使用elasticsearch作为haystack的后端。我按照here创建了搜索所需的所有内容。但是当我搜索时，我发送了一个带有TransportError的追踪错误（400，＆＃39; parsing_exception＆＃39;，＆＃39;没有[查询]注册[过滤]＆＃39;）。

我已经用Google搜索了这个问题。但是没有得到任何解决方案。我很乐意帮助我解决这个问题。

我的追溯：

//Reload Question List when User enter the Game view.
questionService.initialize().done(function(){
  //Now we got question, initialize the Game View
    questionService.getQuestion().done(
      function (data) {
        console.log(data);
        slider.slidePage(new GameView(data).render().$el);
      })
});

Update-1：TraceBack降级为elasticsearch == 1.7.0

Answer 1

没有[查询]注册[过滤]

从我可以看到您运行的是ES 5.0，您发送的filtered查询已在ES 2.x和removed in ES 5.x中弃用。

您需要将其替换为bool/filter query。

所以如果你有这样的事情：

{
  "query": {
    "filtered": {
      "filter": {}
    }
  }
}

只需用

替换它

{
  "query": {
    "bool": {
      "filter": {}
    }
  }
}

Answer 2

Elasticsearch已弃用filtered查询。请改用bool。

它对我有用。

Answer 3

根据haystack docs要解决此错误，您应该在设置中设置正确的haystack引擎后端版本。对于Elasticsearch v 5.x.x，它将是

H_ENGINE = 'haystack.backends.elasticsearch5_backend.Elasticsearch5SearchEngine'
