windows 10 – How can I fuzzy search a pdf file

I’d like to look for textual information in pdf files where words are not necessarily linked together. For example, I’d like to input “Super” and “question” and have the following sentence in the output (if it is in the pdf file):

Super User is a question and answer site for computer enthusiasts and power users.

How can I achieve this? If this is not possible can I do it in txt? Preferably the solution should also show the search context (a few lines up and below) and is fast enough (through indexing?).

Thank you very much!
