Is there is a way to "load balance" 2 index in elasticsearch?

Question

Let say we have 2 index that contains almost similar data.

Example:

• index_1 // contains some data
• index_2 // contains some data (likely the same one)

Does there is a way to use an alias to access them, but only get results from one of it ?

One way could be to do that clientside -> fetch all the indices that the alias point and then query one of it -> but it is adding complexity in client side Right now I tried with alias pointing to index_1 and index_2 -> but it is merging the results of the 2 index.

Answer 1

What you are trying to do is not possible and you have to do it from your side only or use Opster's multi-cluster load balancer if you have advance use cases.

If you want to protect your elasticsearch cluster from bad/costly searches than you might also have a look at search gateway
