Csquery

Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file lib/csquery. To experiment with that code, run bin/console for an interactive prompt.

A simple query builder for Amazon Cloudsearch Structured query parser for ruby. see: https://github.com/tell-k/csquery

Installation

Add this line to your application's Gemfile:

gem 'csquery'

And then execute:

$ bundle

Or install it yourself as:

$ gem install csquery

Usage

builder = Csquery::Structured::Builder.new(:and_) do
  not_('test', field:'genres')

  or_ do
    term_('star', field:'title', boost:2)
    term_('star', field:'plot')
  end
end

builder.query
# => "(and (not field=genres 'test') (or (term field=title boost=2 'star') (term field=plot 'star')))"

You can also build a query manually without the DSL:

Csquery::Structured.and_(
    Csquery::Structured.not_('test', field:'genres'),
    Csquery::Structured.or_(
        Csquery::Structured.term_('star', field:'title', boost:2),
        Csquery::Structured.term_('star', field:'plot')
    )
).query
# => "(and (not field=genres 'test') (or (term field=title boost=2 'star') (term field=plot 'star')))"

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
