HI,

Im using Java High level rest client version 7.17.5. Multi Search API not working as expected. 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

Hi @sheiks2m

I believe it's because the [code](https://github.com/elastic/elasticsearch/blob/main/server/src/main/java/org/elasticsearch/action/search/MultiSearchRequest.java#L278) expects a "type" but it's sending "types".  
I don't know if it's a mistake so open a doubt in git.

Hi I'm having the exact same issue myself.

Did you manage to find a work around / fix?

Thanks
