elasticsearch 使用Java API将elasticsearch限制为给定索引

我有以下代码用于在ES中搜索：

    Header[] headers = {new BasicHeader(HttpHeaders.CONTENT_TYPE, "application/json"), new BasicHeader(HttpHeaders.CONNECTION, "keep-alive")};
    RestClientBuilder restClientBuilder =
            RestClient.builder( new HttpHost("my-es-url",
                    443, "https"));
    restClientBuilder.setDefaultHeaders(headers);

    RestHighLevelClient client = new RestHighLevelClient(restClientBuilder);

    SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
    sourceBuilder.query(QueryBuilders.rangeQuery("createdAt").from(startDate).to(endDate));
    SearchRequest searchRequest = new SearchRequest();
    searchRequest.source(sourceBuilder);

    SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);
    System.out.println(searchResponse.getHits().getHits().length);

这个很好用。但是我发现我没有在这里提供索引名。我只想将搜索限制在给定的索引内

如何配置它？

您可以在创建

搜索请求时这样做：

SearchRequest searchRequest = new SearchRequest("my-index");
