Overview

Static collection implementation.

This kind of collection is for situations where your index usually doesn’t change but instead is rebuilt from scratch once in a while.

This collection keeps two indexes, one for searching, and one where all index modifications take place. Once you are finished building the new index, call the switch method to put it live. The old index is then dropped and the new one is used for searching from now on.
