Hi Search Enthusiasts
Hybrid Search scenario is one of the major steps in integrating your SPO and OnPrem SP2013 environments.
I just wanted to list down the phases and documentation links that are relevant in setting an Hybrid Search Topology. The set up process is lengthy hence it is important to keep in mind the overall picture of what needs to be done.
# PHASE 1 - Configure a Hybrid Topology
Configure a one-way outbound hybrid topology [OnPrem->SPO]
Configure a one-way inbound hybrid topology [SPO->OnPrem]
Configure a two-way hybrid topology [OnPrem<->SPO]
# PHASE 2 - Configure a reverse proxy device (Inbound / Two-Way ONLY)
# PHASE 3 - Configure identity management for a hybrid topology
# PHASE 4 - Configure a Hybrid Solution (Search, BCS, Duet)
To see a concrete example of setup you can refer to the below blogs
Have a good one !
