使用Java在elasticsearch中更新多个文档。我正在使用Elasticsearch 2.3.2

Question

我想使用Java API用一个特定的字段更新一些索引数据。我参考了这个文档https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-docs-update.html，并创建了一个java程序。我的Java程序如下所示：

public class App {

  public static void main(String[] args) throws Exception {
    Client client = TransportClient.builder().build().addTransportAddress(
        new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"),
            9300));
UpdateRequest updateRequest = new UpdateRequest("pibindex", "SearchTech",
        "http://www.sea.com/bundle")
            .script(new Script("ctx._source.default_collection = \"true\""));
    client.update(updateRequest).get();
   }
}

POST /pibindex2/_update_by_query
{
  "script": {
    "inline": "ctx._source.wiki_collection=true"
  },
      "query": {
        "wildcard": {
          "url": {
            "value": "http://www.sea.com/bundle/*"
          }
        }
      }
}

Answer 1

您可以尝试这样做：

import static org.elasticsearch.index.query.QueryBuilders.wildcardQuery;

BulkIndexByScrollResponse r = ubqrb.source("twitter")
    .script(script)
    .filter(wilcardQuery("url", "http://www.sea.com/bundle/*"))
    .get();

尽管结果将取决于是否分析了URL字段。
