Right now I am seeing if a sentence contains a specific word by splitting the sentence into an array and then doing an include to see if it contains the word. Something like:

"This is my awesome sentence.".split(" ").include?('awesome')

But I'm wondering what the fastest way to do this with a phrase is. Like if I wanted to see if the sentence "This is my awesome sentence." contains the phrase "my awesome sentence". I am scraping sentences and comparing a very large number of phrases, so speed is somewhat important.
