Structured Search 
StructuredSearch is a Rubygem for querying search engines, APIs and other information providers by using SQL statements (Yeah, just like the ones you use in mySQL! ...kinda)
- Supports multiple search terms with multiple search providers
- Customisable provider configurations allow for modifiable COUNT, MAX, MIN methods.
Installing StructuredSearch
$ gem install structured_search
or in your Gemfile:
gem 'structured_search'
How to use StructuredSearch
There are two path you can go by, the easiest method is to just pass your input and your list of providers into the evaluate method:
require 'structured_search'
# a hash of your providers, the key should be the same case as
# seen in your input, and the values are classes that contain the
# class method 'search'.
providers = {
:Google => MySearchProviders::GoogleSearchClass,
:Github => GithubApi::StructuredSearchProviderClass
}
# the SQL string to evaluate
search_query = "SELECT 'Matz', 'Ruby' FROM 'Google';"
results = StructuredSearch.evaluate(search_query, providers)
# and read your results:
# they're contained in an array (each statement), addressed by
# the provider (i.e. Google) and then by search term
ruby_google_results = results[0]['Google']['Ruby']License
