Why Google Search Results are Empty
When you do the search on Google for adult language words the search results may appear to be empty. This is due to the nature how Google search handles what you type in the search box. If instant search is enabled every part of the word you typed is sent to Google search server instantly.
If this search term contains adult word that need to be blocked then Web Safety blocks such request and returns the standard 403 Not Allowed response. Google page running in your browser does not know what to do in this case and displays empty results.
The following screenshots show the empty search page and blocked report in the Surfing Now page of Web Safety UI. Unfortunately it is not yet known how to overcome this limitation.
