elasticsearch - 没有为[query]注册的查询]

Question

我正在尝试从我的测试中向ES发送请求。 I applied mapping and inserted documents to ES index named 'gccount_test' from the same test。我在一个名为member的文件中维护了一个非常简单的查询，我想测试它。

{
    "query" : { 
          "match_all" : {} 
     }
}

我的测试方法是

public void testMemberQuery(){
        final Charset CHARSET = StandardCharsets.UTF_8

        //load query
        byte[] bytes = Files.readAllBytes(Paths.get(MEMBER_QUERY_PATH))
        String query = CHARSET.decode(ByteBuffer.wrap(bytes)).toString()

        println "QUERY => ${query}"

        SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder()
        searchSourceBuilder.query(query)

        SearchRequestBuilder searchRequestBuilder = client.prepareSearch(INDEX_NAME)
        //ClusterAdminClient adminClient = client.admin().cluster()
        //searchRequestBuilder.setTypes(Constants.ESTYPE_MEMBER)
        //println "CLUSTER => ${adminClient}"

        searchRequestBuilder.setSearchType(SearchType.QUERY_THEN_FETCH);
        searchRequestBuilder.internalBuilder(searchSourceBuilder)

        SearchResponse searchResponse = searchRequestBuilder.execute().actionGet()
        println "Search Response => ${searchResponse.toString()}"

        //blah blah 
    }

不幸的是，我收到了以下错误。

Failed to execute phase [query_fetch], total failure; shardFailures {[1][gccount][0]: SearchParseException[[gccount_test][0]: from[-1],size[-1]: Parse Failure [Failed to parse source [{"query_binary":"ewogICAgInF1ZXJ5IiA6IHsgCiAgICAgICAgICAibWF0Y2hfYWxsIiA6IHt9IAogICAgIH0KfQ=="}]]]; nested: QueryParsingException[[gccount_test] No query registered for [query]]; }

我正在使用elasticsearch 0.90.2 dependecy

[group: 'org.elasticsearch', name: 'elasticsearch', version: '0.90.2']

同样的事情在真实环境中运行良好（下面的快照）

从文件加载查询时出现问题是导致错误还是什么？

Answer 1

该异常基本上意味着“没有名为query的已知查询类型”。我猜你的客户端库是自动插入顶级query属性的，所以你生成的查询实际上是这样的：

{
    "query" : {
        "query" : { 
          "match_all" : {} 
        }
    }
}

如果您的客户端可以转储查询的JSON表示，那么这可以帮助调试。

尝试从文本文件中删除query部分，以便它只是match_all查询，看看它是否适合您。

Answer 2

您的查询字符串应为

String query = "{\"match_all\":{}}";
