Opensearch vs opensearchapi module in Go

Describe the issue:

I have a confusion regarding which of the the following modules in the OpenSearch Go client I need to use. I am writing a Go program that fetches data from OpenSearch. I will later be extending it to create monitors in OpenSearch.

github.com/opensearch-project/opensearch-go/v4
github.com/opensearch-project/opensearch-go/v4/opensearchapi

The example in OpenSearch Go documentation uses the opensearchapi module as follows to perform a search operation.

content := strings.NewReader(`{
    "size": 5,
    "query": {
        "multi_match": {
        "query": "miller",
        "fields": ["title^2", "director"]
        }
    }
}`)

search := opensearchapi.SearchRequest{
    Index: []string{"go-test-index1"},
    Body: content,
}

searchResponse, err := search.Do(context.Background(), client)

However, the example in the user guide in the GitHub repository uses the opensearch module to perform the search request

// Search for the document.
content := strings.NewReader(`{
	"size": 5,
	"query": {
		"multi_match": {
			"query": "miller",
			"fields": ["title^2", "director"]
		}
	}
}`)

searchResp, err := client.Search(
	ctx,
	&opensearchapi.SearchReq{
		Body: content,
	},
)

My question is, what is the recommended module to use? Is it opensearch or opensearchapi ?
