Module: Unitwise::Search

Defined in:
lib/unitwise/search.rb

Overview

The search module provides a simple search mechanism around known basic units. The full list of avaliable units infinite, so this search creates a small subset of atoms and prefixes to help users find what they are looking for. Thus, there is a multitude of valid units that may be constructed that this module will not be aware of.
