Django/Haystack error: 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。如前所述，我创建了搜索所需的一切 here。但是当我搜索时，我会抛出一个带有 TransportError(400, 'parsing_exception', 'no [query] registered for [filtered]') 的回溯错误。

我已经用谷歌搜索了这个问题。但是没有得到任何解决方案。如果能帮我解决这个问题，我将不胜感激。

我的回溯：

Update-1：降级到elasticsearch==1.7.0后的TraceBack

Answer 1

no [query] registered for [filtered]

据我所知，您是运行 ES 5.0，并且您发送的 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": {}
    }
  }
}

只需将其替换为

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

Answer 2

Elasticsearch 已弃用 filtered 查询。请改用 bool。

对我有用。

Answer 3

根据 haystack docs 要修复此错误，您应该在设置中设置正确版本的 haystack 引擎后端。对于 elasticsearch v 5.x.x 它将是

H_ENGINE = 'haystack.backends.elasticsearch5_backend.Elasticsearch5SearchEngine'
