fix: getQuerystringSearchQuery doesn't accept path as an input

[askadityapandey]

This Pull Request fixes #6254 , which is "Without being able to pass in a path to the querystring-search, all searches are performed from the root, breaking relative queries (e.g. ../::1)"
I've added all the important tests which are required, also made it optional so it does not break for the existing users.
This is a cool project btw, will look forward to contribute more <3
