java - Elasticsearch MultiSearchRequestBuilder

Question

我已经编写了一个查询，并希望在每个查询执行上动态设置索引。如何传递索引名称。

MultiSearchRequestBuilder multiSearchRequestBuilder = null;
 multiSearchRequestBuilder = client.prepareMultiSearch()

Answer 1

您需要为要对您选择的任何索引发出的每个请求构建一个 SearchRequest，然后将该 SearchRequest 添加到 MultiSearchRequestBuilder

SearchRequest searchRequest1 = new SearchRequest("index1"); 
multiSearchRequestBuilder.add(searchRequest1);
SearchRequest searchRequest2 = new SearchRequest("index2"); 
multiSearchRequestBuilder.add(searchRequest2);
