Home google-correction
Search Google without automatic correction
An ordinary search field. The result opens on Google for the term you typed, without the automatic swap for a corrected version.
Automatic correction Off for this search
The search opens with nfpr=1. What you type goes straight to Google. This page never sees the text.
What nfpr=1 asks for
When Google thinks the term is wrong, it replaces the query and shows results for the corrected spelling. Above the list, it says it is showing results for the other form.
nfpr=1 asks it not to make that swap. The search stays with what was typed: a proper name, a brand, an abbreviation, or a mistake left on purpose.
The address carries nfpr=1. After you search, it is there in the address bar. The account stays as it is, and the request applies to that query.
A loose suggestion can still appear on the page. What drops out is the automatic replacement of the query by another one.
