Hi, I'm wondering if this is a supported scenario in ElasticSearch, reading the guide and API reference I couldn't find a way to achieve this. I'd like to index documents only once, say in a master index, and then create secondary or "meta" indices that would only contain a subset of the master index. For example, document A, B and C would be indexed once in the master index. Then a secondary index would be able to see only documents A and B, while another secondary index could see only documents B and C, etc. (and by "see" I mean the search queries should only consider those documents) The idea being that documents could be relatively big, and they should not be indexed multiple times. Does that make sense? Am I missing "the right way" to design such a pattern? I am new to ES.

This isn't something that can be done natively in ES. You could however have index A, B and C that you can apply a replication factor to, then use aliases to group them into logical units.
