Issue/Introduction

Edge SWG admins may be looking for an option to block AI Mode search in the Google search portal.

Resolution

Option 1 - Simple policy to block Google AI Mode search

The following CPL policy should block AI Mode as of now:

<proxy>
url.domain=google.com url.path.substring=search url.query.substring="udm=50" deny

 

Option 2 - Extended policy to enforce regular search for Google search queries 

define condition Method_CONNECT
    http.method=(CONNECT)
end condition Method_CONNECT

<proxy> condition=!Method_CONNECT
url.domain=google.com url.query.regex=!"" action.GoogleAIMode_rewrite1(yes)
url.domain=google.com url.query.substring="udm=" action.GoogleAIMode_rewrite2(yes)
url.domain=google.com url.path.substring=search url.query.substring=!"udm=" action.GoogleAIMode_rewrite3(yes)


define action GoogleAIMode_rewrite1
  rewrite(url, "^(.*)$", "$(1)/?udm=14")
end

define action GoogleAIMode_rewrite2
  rewrite(url, "^(.*)udm=\d+(.*)$", "$(1)udm=14$(2)")
end

define action GoogleAIMode_rewrite3
  rewrite(url, "^(.*)$", "$(1)&udm=14")
end

Additional Information

Please note that Google may change AI Mode search query parameters with time hence the policy rule may stop working.
