SharePoint stretched farm
Installed SharePoint as a Google like search engine for documents on filers. Configuring it as a stretched farm (servers in multiple sites) with a SQL backend. This is overkill for a search site, but makes it possible to failover SharePoint to DR site an will be useful if it’s used as a doc library in future, or for SQL 2014 data analytics. Also SharePoint automatically shares the indexing work between servers in a farm.
