Is there possibly no official documentation for Windows 11 search?

I have looked far and wide to find a definitive, official technical reference for the Windows 11 search service... especially for the various search parameters and the syntax they require from a savvy user to conduct a well specified, precision search for something. Is it possible that Microsoft has not produced a formal specification of Windows' search feature?

Would someone from Microsoft please, please, please provide a link to such a document? Is it possible to buy it? Does it exist anywhere? Am I deluded to think that that is something that the provider of the world's most used desktop OS would have had to create, as a matter of course? 

I'm talking here about conducting searches, within the file system of a Windows 11 (Pro) machine, that one initiates from the "Search Home" box at the top right of every File Explorer window that gets opened by the user.

Any thoughts from someone actually involved in creating the search tool?

Imploringly yours,
