elasticsearch - 使用_search而不是GET找到的文档

Question

我们有一台机器 flex 搜索服务器(8个分片，但全部托管在同一台机器上)。索引包含700万份文档。在为文档建立索引时，我们不指定任何自定义路由。我们正在使用Elastic search 1.2版。

问题是我们无法使用GET检索许多文档。但是，使用search？_id:我们可以检索所有这些文档。

通过使用GET指定路由参数(具有不同的值(1,2,3，...))，我们也成功地检索了文档。

在以前的版本(即Elastic Search 1.0.3)中，我们没有这个问题。

有解决的建议吗？

提前致谢

Elasticsearch 1.2.0中有一个错误会导致此特定行为。这是由于1.2.0中引入的路由错误所致:

There was a routing bug in Elasticsearch 1.2.0 that could have a number of bad side effects on the cluster. Possible side effects include:

• documents that were indexed prior to the upgrade to 1.2.0 may not be accessible via get. A search would find these documents, but not a direct get of the document by ID.

• documents that were updated after the upgrade to 1.2.0 may be duplicated, with one copy from pre-1.2.0 and a second copy updated
  since the upgrade to 1.2.0.

• if a document is duplicated as above, and versioning is in use, the document added after the upgrade to 1.2.0 will have its version
  reset.

ES建议所有人立即升级到1.2.1。关于如何解决使用1.2.0插入或更新引入的索引损坏问题，目前尚无任何消息。详细信息在这里:
