Let's say I turn a whole page of text into a single vector. This page includes different kinds of information, e.g. my passwords, birthdates, book titles, all kinds of stuff.
Now I create a query about one single thing, .e.g.: "What is my WiFi password?"
Will the large page vector be positioned close to my query's vector, even tho the page contains a bunch of different information? Or do I need to slice the large page up into several separate vectors to get good results?
