Full-text search in Ruby with picky

Hey guys,

I just migrated my bus and tramway webapp search engine to Picky, a wonderful gem that I found that makes full-text REALLY easy.

First step, add picky to your Gemfile.

Then, update the model :

class Stop < ActiveRecord::Base
 after_save :reindex

 def reindex
 StopIndex.replace self
 end

 def self.search s
 ids = (StopSearch.search s).ids
 where "id in (?) and enabled is true", ids
 end

end

And finally, add an initializer config/initializers/picky.rb

if Stop.table_exists? then
 StopIndex = Picky::Index.new :stops do
 source Stop.all

 # This will add all attributes to the index.
 Stop.attribute_names[1..-1].each do |cname|
 category cname.to_sym
 end
 end

 StopSearch = Picky::Search.new StopIndex

 begin
 # Try to load the index from cache.
 StopIndex.load
 rescue
 # Index on first boot or on database changes.
 StopIndex.index
 end

 # Save the index program exit.
 at_exit { StopIndex.dump }
end

#rails

#full text search

#picky
