"如何在 elasticsearch(6.4.3) 中使用 deleteRequest API 刪除索引"

Question

我想使用 DeleteRequest API 刪除 elasticsearch 6.4.3 中的索引

但是 elastic.co 指南 3 個參數（索引、文檔、id）（ https:\/\/www.elastic.co\/guide\/en\/elasticsearch\/client\/java-rest\/6.4\/java-rest-high-document-delete.html<\/a> )

我想使用 2 個參數來刪除索引（索引、文檔）

那么，有人幫我解決這個問題嗎？

DeleteRequest deleteRequest = new DeleteRequest(index);
DeleteResponse response = mClient.delete(deleteRequest, RequestOptions.DEFAULT);

Answer 1

DeleteRequest request = new DeleteRequest(
    "index",   
    "doc",     
    "id");
DeleteResponse deleteResponse = client.delete(request,RequestOptions.DEFAULT);
        return deleteResponse.getResult().name();

其中“ index”是索引名稱，id是文檔ID。

根據https://www.elastic.co/guide/zh-CN/elasticsearch/client/java-rest/6.4/java-rest-high-document-delete.html文檔，您需要傳遞3個參數。 2參數應為“ doc”。

Answer 2

如果要在 Elastic Search 中刪除索引，則需要使用刪除索引 API https:\/\/www.elastic.co\/guide\/en\/elasticsearch\/client\/java-rest\/6.4\/java-rest-high-delete -index.html<\/a>

這是基本示例，使用同步執行：

DeleteIndexRequest request = new DeleteIndexRequest(*IndexName*);
DeleteIndexResponse deleteIndexResponse = client.indices().delete(request, RequestOptions.DEFAULT);
