Hi,
Im using elasticsearch 8.3.2. Im facing the issue while using multi search api.
API: [https://elasticrunningserver:9200/myindex/\_msearch](https://elasticrunningserver:9200/myindex/_msearch)
Payload:
```auto
{ }
{"query" : {"match" : { "message": "this is a test"}}}
{"query" : {"match_all" : {}}}
```
Response:
```auto
{
"error": {
"root_cause": [
{
"type": "illegal_argument_exception",
"reason": "key [query] is not supported in the metadata section"
}
],
"type": "illegal_argument_exception",
"reason": "key [query] is not supported in the metadata section"
},
"status": 400
}
```
Please guide me how to fix this.
- Thanks

Hi @sheiks2m
Read more about [Multi Search API](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-multi-search.html)
The correct example is
```auto
GET my-index-000001/_msearch
{ }
{"query" : {"match" : { "message": "this is a test"}}}
{"index": "my-index-000002"}
{"query" : {"match_all" : {}}}
```

Execute with this payload:
```auto
{ }
{"query" : {"match" : { "message": "this is a test"}}}
```
After add new query:
```auto
{}
{"query" : {"match" : { "message": "this is a test"}}}
{}
{"query" : {"match_all" : {}}}
```
Tell me if it worked

Hi @RabBit_BR ,
Thanks for your response. Its working fine as expected.
But another scenario, Im using Java High level rest client version 7.17.5. Im applying the same but it doesnt work. Please find the below code
```auto
SearchSourceBuilder metaDataSearch = new SearchSourceBuilder();
org.elasticsearch.action.search.SearchRequest metaSearch = new org.elasticsearch.action.search.SearchRequest().source(metaDataSearch).indices(indexName);
SearchSourceBuilder keywordExactRequestBuilder = new SearchSourceBuilder().size(10);
keywordExactRequestBuilder.query(QueryBuilders.matchAllQuery());
org.elasticsearch.action.search.SearchRequest keywordExactRequestSearch = new org.elasticsearch.action.search.SearchRequest().source(keywordExactRequestBuilder).indices(indexName);
MultiSearchRequest multiSearchRequest = new MultiSearchRequest()
.add(metaSearch)
.add(keywordExactRequestSearch);
MultiSearchResponse multiSearchResponse = null;
try {
multiSearchResponse = elasticClient.msearch(multiSearchRequest, RequestOptions.DEFAULT);
} catch (IOException e) {
e.printStackTrace();
}
```
Im facing the below exception
```auto
org.jboss.resteasy.spi.UnhandledException: ElasticsearchStatusException[Elasticsearch exception [type=illegal_argument_exception, reason=key [types] is not supported in the metadata section]]
.......
Caused by:
ElasticsearchStatusException[Elasticsearch exception [type=illegal_argument_exception, reason=key [types] is not supported in the metadata section]]
......
```
Im enabled API compatibility mode. Im using elasticsearch version 8.3.2
Thanks

You are better off creating a new topic for that as it's a different client library 🙂
