Hi,

I am using ElasticSearch ver. 6.2.3 and I have created three indexes

1. MasterSubscribers
2. CustomSubscriber1
3. CustomSubscriber2

each of these have common doc type "Subscriber"

All these indexes currently have data which we pushed from 3 SQL databases. Master may or may not have all subscribers details.  
If Subscriber is not found under 1st index then it should search under 2 & 3 index.

How can i write query for this? Can i join multiple indexes?

Thanks!

Hi,

Do you want to join the indexes and find common fields or search for a field across indices?

If you want to search for a field across indices, you can use the `Multi-index` api to do so easily. Let me know if this helps.
