# Plagiarism

Search for plagiarism and check the duplication of your content from Bing, Google, Yahoo and DuckDuckGo.

## Installation

```ruby
gem 'plagiarism2', require: 'plagiarism'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install plagiarism2

## Usage

Add in your config

```ruby
Plagiarism.configure do |config|
  config.strategies = [xxx] # => [:google, :bing, :duck, :yahoo, :free_google]
  config.whitelists = ['www.ring.md']
end
```

> There is a limit in using duck, yahoo and free google. If you spam request, they will mark you as spam

+ Using bing engine, you have to set access key (you can get it from [here](https://datamarket.azure.com/dataset/bing/searchweb))

```ruby
config.strategies = :bing
config.bing_key = xxx
```

+ Using google engine (not free google), you have to set two keys (you can get it from [here](https://developers.google.com/custom-search/json-api/v1/using_rest))

```ruby
config.strategies = :google
config.google_key = xxx
config.google_cx = xx
```

###### Plagiarism.unique?

```ruby
text = 'Latte user story paradigm affordances experiential innovate venture capital physical computing. Ship it agile actionable insight iterate thought leader pitch deck experiential iterate. Venture capital food-truck quantitative vs. qualitative SpaceTeam convergence agile.'
Plagiarism.unique? text # => true
