Exclude indexes in java search API

Elastic Stack Elasticsearch
1

Hi,

I am using elasticsearch 5.4.1.
I create queries using JAVA API and until now we had 5 indexes.
I always searched all 5 of the indexes and in order to achieve this, I didn't send index names with the search request.
Now we are going to add a 6 index and now there are 2 usecases:

  1. search the 6th index alone - just send its name with the search request.
  2. search all indexes excluding the 6th.

I can't give the 5 indexes names hardcoded in the request since they are deleted and created dynamically by the system (with random names).
So I need to maintain a list of indices in memory and modify this list when it changes in ES.
I don't like this so much and wanted to have an API in JAVA that can tell ES to search all indexes except the 6th (that has a constant name).
Can it be done?

Thanks

I'd use an index template which sets an alias for the new index automatically. Then you just have to query the alias.

Thank you
