One of logical reason I can think of is that Check Point wants to prevent DDoS attacks or huge demand using search function by some bots.
Or simple allow searching only for Customers and Partners.
Wondering how this new feature will have impact on google results/cache.
On the other side, majority of all articles require you to log in to see Solution. So you have to be logged in in order to see the Solution (even if it is just "Contact Check Point and be ready with cpinfo").
