Sometimes I want to find a word in a document, but I want the context for the word. Write a function that takes a document and a word and returns the sentences that contain that word. The sentences should be returned in the order they appear in the document.
(search "This is my document." "Hello") ;=> nil (search "This is my document. It has two sentences." "sentences") ;=> ["It has two sentences."] (search "I like to write. Do you like to write?" "Write") ;=> ["I like to write." "Do you like to write?"]
Sentences end with
The search should be case insensitive.
nil if the word is not found.
