java - 如何在ES API Java中创建多重索引

Question

我的索引是:https://URL/bpa_stag_v3_2016*,bpa_stag_v3_2017/orders_suppliers_stats_ag/_search 我正在使用 api java 进行 Elasticsearch ，但它不起作用。

  String indexForTwoYear = ConfiguratorDao.CURRENT_ENV.getAliasPrefix() + String.valueOf(previousYear) + "*,"
                    + ConfiguratorDao.CURRENT_ENV.getAliasPrefix() + String.valueOf(currentYear) + "*";



            SearchRequestBuilder requestBuilder = client.prepareSearch(indexForTwoYear)
                    .setTypes(IndexTypeEnum.SUPPLIERS_AGGREGATION.getValue()).setQuery(queryBuilder).setSize(1);

Answer 1

根据 Elasticsearch 的 AbstractClient 类(由 NodeClient 和 TransportClient 扩展)的文档，您可以传递可变数量的索引作为 prepareSearch 方法中的 var-args (javadoc here ):

public SearchRequestBuilder prepareSearch(String... indices)

Search across one or more indices and one or more types with a query.

所以，就你的情况而言，它是:

client.prepareSearch("pa_stag_v3_2016*","bpa_stag_v3_2017")
