Pega Search Multinode syncing
In an environment with, for example, 3 index nodes with Search Index fully in sync.
If node #1 goes down for 30 minutes then comes back online. Does Pega know what the missing delta was and syncs it? How does it sync it?

Hi,
I think it will work because as soon as third node comes up,It will be able to _search_ the index (by communicating to the ElasticSearch-enabled nodes); even if it doesn't have the indexes present.
Please go through the following link where you can find a very good example of search with various cases.

Hello Ming,
As per my understanding, in an ideal scenario, Pega will take care of the missing index and would copy the index from the node which was up and running to the node which went down for 30 mins as soon as it is back online.
Basically, the system replicates the indexes on the new nodes joining the cluster as the search index host node.
Thank you,
Pawan
