What is a good way to represent files semantically for vector search

I recently had an idea that is it possible to make a software service which could help me search files from my files system though context of content inside the files. So like i can search "where is the file which contained x thing" and get would a list of files that would match my question. So I don't want sear or keywords but ch by file name context. Also for all types of files like iamge, text, video, audio, code etc So I kept thinking about it and knew that the answer lied within vector search. I initially thought that maybe if somehow I could represent an entire file in a singular vector
