Every single document “page” humans index has three “interesting” dimensions: the height and width of the page the words appear on, plus another for the font size. So, what is a document anyway? Is a file handle just another type of dimension? Or, is a picture on the page part of the page document, or is it its own document? Humans use arbitrary dimensions to tokenize the document’s bits, so to speak. My dad could read a book (a big document) in blocks or chunks. In thinking of it that way it become apparent that groups and positions of data may constitute their own document boundaries and that info may be used in both the indexing and search pipelines to build relevance and relatedness.
