Filter Adult Content in Search Engines - 40F

Hi,

I'm not sure it is even possible.

I have 40F running version 7.2.11

I understand that I can configure 40F to do SSL Inspection and Web Filtering - to block adult websites (not sure how - a guide would be great).

I've been asked to block the following situation - 

when a person enters Google and over google search for "porn" or "xxx" etc - the following should occur - 

1.at best option - the whole search will be blocked.

2.in case option 1 is impssible - would it be possible to block the images that you can see when going to "Images" and "videos" tab under the google search ?

the situation is that the images tab for example shows previews of porn websites without entering them.
