Question: How to implement a user search across several servers?

Hi

we are planing to run several servers around the world and would like to have a contact search from the client (that is Spark) across all servers.

Any idea how to do that? Extend the search plugin ? Extend Spark ? What would be an appropriate architecture ?

Extending searching plugin is better way to do so. Which internally make request to other server by s2s communication. So User has to search only one user directory.
