twitter-search's Introduction

Twitter Search powered by Algolia

This is the Rails 4 application providing Twitter Search. It's based on algoliasearch-rails and uses Twitter's Streaming API to crawl new users.

Configuration

class Handle < ActiveRecord::Base
  include AlgoliaSearch

  algoliasearch per_environment: true do
    # add an extra score attribute
    add_attribute :score

    # add an extra full_name attribute: screen_name + name
    add_attribute :full_name

    # do not take `full_name`'s words order into account, `full_name` is more important than `description`
    attributesToIndex ['unordered(full_name)', :description]

    # list of attributes to highlight
    attributesToHighlight [:screen_name, :name, :description]

    # use followers_count OR mentions_count to sort results (last sort criteria)
    customRanking ['desc(score)']

    # @I_love_you
    separatorsToIndex '_'

    # tag top-users
    tags do
      followers_count > 10000000 ? ['top'] : []
    end
  end

  def full_name
    "#{screen_name} #{name}"
  end

  # the custom score
  def score
    return followers_count if followers_count > 0
    if mentions_count < 10
      mentions_count
    elsif mentions_count < 100
      mentions_count * 10
    elsif mentions_count < 1000
      mentions_count * 100
    else
      mentions_count * 1000
    end
  end

end
