Method: Sunspot::InstantiatedFacet#populate_instances!

Defined in:
lib/sunspot/instantiated_facet.rb

#populate_instances! ⇒ Object

Hydrate all rows for the facet. For data accessors that can efficiently batch load, this is more efficient than individually lazy-loading instances for each row, but allows us to still stay lazy and not do work in the persistent store if the instances are not needed.
