Google Custom Search
This project is a Ruby API to Google's Custom Search Engine (www.google.com/cse). This plugin is rewrite plugin from Alex Reisner (github.com/alexreisner/google_custom_search.git), because the old plugin not working.
Install either as a Rails plugin:
rails plugin install git://github.com/vodafon/google_cse.git
or as a gem:
# add to Gemfile: gem "google_cse" # at command prompt: bundle install
or as a standalone gem (outside of Rails):
sudo gem install google_cse
You must define a constant in your application called CX_GOOGLE_CSE. For example, if you're using Rails, create a file config/initializers/google_cse.rb:
CX_GOOGLE_CSE = "..."
You can find the CX value for your custom search engine via the search control panel on Google's site (click the “Get code” link and you'll see a hidden “cx” field in the sample HTML form).
To perform a search:
results = GoogleCustomSearch.search("Hank Aaron", 0)
The second parameter is a start parameter for search query. 0 - first page (1-10 result), 10 - second page, etc.
The results variable is now a GoogleCustomSearch::ResultSet object:
results.pages # array of pages data results.results # array of result objects
Iterate through the results:
results.results.each do |result| result.title # result title result.url # result URL result.description # excerpt, with terms highlighted end
