scala - 是否有使用sksamuel/elastic4s或其他任何工具的ElasticSearch 5.1.1 Scala API的好示例？

Question

我找不到在sksamuel / elastic4s中使用Scala的ElasticSearch 5.1.1的良好示例。文档不是很有帮助，该站点都没有很好的例子。即使是创建索引，放置数据和搜索的简单示例也将有所帮助。

Answer 1

elastic4s自述文件包含了您需要入门的所有示例。诚然，它只适用于高级用例，但是对于简单的示例来说，有很多。

例如，阅读quick start guide。

import com.sksamuel.elastic4s.TcpClient
import com.sksamuel.elastic4s.ElasticDsl._

object Test extends App {

  // Here we create an instance of the TCP client
  val client = TcpClient.transport(ElasticsearchClientUri(host, port))

  // await is a helper method to make this operation synchronous instead of async
  // You would normally avoid doing this in a real program as it will block your thread
  client.execute { 
    indexInto("bands" / "artists") fields ("name" -> "coldplay") refresh(RefreshPolicy.IMMEDIATE)
  }.await

  // now we can search for the document we just indexed
  val resp = client.execute { 
    search("bands" / "artists") query "coldplay" 
  }.await

  println(resp)
}
