Constructor Details

#initialize(model, &block) ⇒ Index

Create a new index instance by passing in the model it is tied to, and a block to build it with (optional but recommended). For documentation on the syntax for inside the block, the Builder class is what you want.

Quick Example:

Index.new(User) do
  indexes , email

  has created_at

  set_property :delta => true
end
