cache

Hello- unfortunately your query is rather vague and unclear.

Would you care to specify the type of search, originating from where, to which you might be referring?

A screenshot of what you are seeing would help, as your reference to cache in this context is not familiar.
To post a screenshot use the icon above your post with tooltip 'Insert Image'.

Here are some examples:

a. Browser search: - which browser, which search engine?
b. Search in Settings
c. Search using the search field on the taskbar or Win key + S
d. Search using file explorer's search field.
e. Indexed or non-indexed search.

If you are referring to Windows indexed search, please read this article - try searching it for 'cache'.
It may suggest what your search is trying to access.
