在弹性搜索中删除别名和索引

Question

I am working on elastic search and I have the following situation.

1. I have two indices index1 and index2.
2. Alias1 points to index1 and index2.
3. Alias2 points to index2.

I would like to delete all of them. Do I need to delete index1, index2 and then delete aliases ? Will the aliases exist if I delete both the indices ? If they exist, what are the java API's to delete those aliases ?

Answer 1

Once you have deleted your index, the alias will also get deleted.

In your case, you can directly delete index1 and index2.

Note: I've experimented it in ES 1.7

Answer 2

如果要删除别名而不是索引，请先删除别名，然后删除索引
