- import org.elasticsearch.common.unit.TimeValue;
切換
+ import org.elasticsearch.core.TimeValue;

在catalina.out會出現
2022-05-23 10:51:48,551 WARN [org.elasticsearch.client.RestClient] 
- request [POST http://{aaa}/{bbb}/_search?

"[ignore_throttled] parameter is deprecated because frozen indices have been deprecated.
Consider cold or frozen tiers in place of frozen indices."]

需調整indicesOptions參數
原本使用:
SearchRequest searchRequest = new SearchRequest(indexName)
.indicesOptions(IndicesOptions.LENIENT_EXPAND_OPEN_CLOSED);
切換使用:
SearchRequest searchRequest = new SearchRequest(indexName)
.indicesOptions(
	IndicesOptions.fromOptions(true, true, true, true, false, true, false, false, true));
最後一個參數 true -> 不查詢frozen index -> 不會出現WARM log
