parse

A method that takes a raw buffer and metadata as parameters and returns a promise that resolves to an array of Document instances. It uses the extractRawText function from the mammoth module or extract method from the word-extractor module to extract the raw text content from the buffer. If the extracted text content is empty, it returns an empty array. Otherwise, it creates a new Document instance with the extracted text content and the provided metadata, and returns it as an array.
