Google search by site keywords?

I’m not sure where I’m supposed to post this but here goes.

Is there a way to search for developed websites on Google with specific keywords within them.

For example: search for all websites containing ‘web’

Than, results include:

‘Webdevelopers .co’
‘Matrix-web.con’
‘Spiderwebbing.com’
‘Webster.uk’

Etc, etc.
