Django/Haystack错误:elasticsearch.exceptions.RequestError:TransportError(400,'parsing_exception',...)

Question

我在我的Django项目中使用elasticsearch作为haystack的后端.我创建了一个搜索如前所述所需的一切在这里.但是当我搜索时,我会抛出TransportError错误(400,'parsing_exception','no [query]注册[filtered]').

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:

Traceback (most recent call last):

更新-1:TraceBack降级为elasticsearch == 1.7.0后

没有为[已过滤]注册[查询]

据我所知，您正在运行 ES 5.0 并且您正在发送一个filtered查询，该查询已在 ES 2.x 中弃用并在 ES 5.x 中删除。

您需要将其替换为bool/filter查询。

所以如果你有这样的事情：

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

只需将其替换为

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