Conditional Indexing with Sunspot

One of my favorite new features of Sunspot 1.3 is the ability to conditionally index an instance of a model based on anything that returns a boolean.

Say I have a Post model to store my blog posts. We want to index only blog posts which are published so users aren't searching on unpublished posts. The syntax looks as follows:

class Post < ActiveRecord::Base
  attr_accessible :title, :content, :published, :external_source

  searchable :if => :published do
    text :title
    text :content

Pretty nice. But let's elaborate a little. Say we want to index only published posts but we don't want to index posts where content comes from an external source.

searchable :if => :published, :unless => :external_source do

Let's flip things around. What if want to index only published blog posts which come from external sources? Supply an array.

searchable :if => [:published, :external_source] do

What if the conditions for indexing are more complex than a simple boolean method on our model? Supply a proc.

searchable :if => proc { |post| post.content.size > 0 } do

Indexing with sunspot just got a whole lot easier.

Happy indexing!
