def initialize(klass)
  @klass = klass
  
  # validate that the class derived from the missing method descends from
  # ActiveRecord and has been "configured" in `Setup.config { setup_tables {...} }'
  # (i.e. "Search.userz.with(...)" where "userz" is an invalid model)
  Validations.validate_class!(@klass)
end

#with(keywords, options = {}) ⇒ Object

used to collect/parse the keywords that are to be searched, and return the search results (hands off to the Rails finder)

Example:

Search.users.with("ryan heath")
# => <#User ... > or []
