elasticsearch - No query registered for [query]]
提问by prayagupd
I am trying to send request to ES from my tests. I applied mapping and inserted documents to ES index named 'gccount_test' from the same test. I have a very simple query maintained in a file named memberthat I want to test.
我正在尝试从我的测试中向 ES 发送请求。我从同一个 test 应用了映射并将文档插入到名为 'gccount_test' 的 ES 索引中。我在一个名为member我要测试的文件中维护了一个非常简单的查询。
{
"query" : {
"match_all" : {}
}
}
My test method is
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
}
Unfortunately, I get following error.
不幸的是，我收到以下错误。

I am using elasticsearch 0.90.2 dependecy
我正在使用 elasticsearch 0.90.2 依赖
[group: 'org.elasticsearch', name: 'elasticsearch', version: '0.90.2']
Same thing runs fine in real environment(snapshot below)
同样的事情在真实环境中运行良好（下面的快照）
Is the problem with while loading query from file that caused it's malformation or what?
从文件加载查询时是否有问题导致其格式错误或什么？

The exception basically means "There is no known query type called query". I'm guessing that your client library is automatically inserting the top-level queryproperty, so your generated query actually looks like this:
异常基本上意味着“没有称为query”的已知查询类型。我猜你的客户端库会自动插入顶级query属性，所以你生成的查询实际上是这样的：
{
"query" : {
"query" : {
"match_all" : {}
}
}
}
If your client can dump the JSON representation of the query, that can help a lot in debugging.
如果您的客户端可以转储查询的 JSON 表示，则对调试有很大帮助。
Try removing the queryportion from your text file so that it is just the match_allquery, see if that works for you.
尝试query从您的文本文件中删除该部分，以便它只是match_all查询，看看这是否适合您。

your query string should be
您的查询字符串应该是
String query = "{\"match_all\":{}}";
