The best way to fix a bug

一名程序员在遇到程序点击按钮后崩溃的问题时,通过一种非常规的方法解决了这个Bug——直接移除了导致问题的按钮。这是一个轻松幽默的故事,提醒我们在面对棘手的技术问题时不妨换个角度思考。

be serious, I am telling a joke:

--“why my program cracked when click the button?”

--“just check the button function, step into it”

 

Hours later…

 

--“Did you fix the bug?”

--“YES!”

 

--“How?”

--“I removed the button.”

In Elasticsearch 7.7, the recommended way to query from multiple indexes using the Transport Java API is to use the MultiSearchRequest API. Here's an example code snippet for querying from multiple indexes using the MultiSearchRequest API: ``` // Create a client object TransportClient client = new PreBuiltTransportClient(Settings.EMPTY) .addTransportAddress(new TransportAddress(InetAddress.getByName("localhost"), 9300)); // Create a MultiSearchRequest object MultiSearchRequest multiSearchRequest = new MultiSearchRequest(); // Add multiple search requests to the MultiSearchRequest object multiSearchRequest.add(SearchRequestBuilders.searchRequest("index1").source(query)); multiSearchRequest.add(SearchRequestBuilders.searchRequest("index2").source(query)); // Execute the MultiSearchRequest MultiSearchResponse multiSearchResponse = client.multiSearch(multiSearchRequest).actionGet(); // Process the response for (MultiSearchResponse.Item item : multiSearchResponse.getResponses()) { SearchResponse searchResponse = item.getResponse(); // Process the search response for each index } // Close the client object client.close(); ``` In this code snippet, we first create a TransportClient object and a MultiSearchRequest object. We then add multiple SearchRequest objects to the MultiSearchRequest object, with each SearchRequest targeting a different index. We then execute the MultiSearchRequest using the client object, and process the response for each index. Note that the above code snippet uses the deprecated TransportClient API. It is recommended to use the Java High Level REST Client or the Java Low Level REST Client instead.
