ElasticSearch 5.1.1 Scala API 使用 sksamuel/elastic4s 或其他任何东西有什么好的例子吗？

Question

我无法在 sksamuel/elastic4s 中找到使用 Scala 的 ElasticSearch 5.1.1 的好示例。文档不是很有用，该站点的 none 有很好的示例。即使是创建索引、放置数据和搜索的简单示例也会有所帮助。

Answer 1

elastic4s 自述文件包含您入门所需的所有示例。不可否认，它对高级用例很简单，但对于简单的例子，有很多。

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)
}
