@WeiZhong Well, since the post on meta is at +15, I considered this strong enough support from community at least to ask moderators about this: Should we add external searches in some help pages about search?

In any case, I have mentioned your response to Daniel Fischer (the mod I talked with): chat.stackexchange.com/transcript/20352/2018/6/29

@MartinSleziak Thank you Martin, I will be glad if they agree to add the link now. But in any case I will keep working on the new model and its implementation.
