When the counts in a Facebook section indicate that all results (1) are shown, it would save me many useless clicks if the Search at the bottom (2) were grayed out - not made non-functional but a visual sign I'd be wasting my time.

To clarify: you'd like the link to still be there (so you can open a Search panel if you choose), but greyed out (or visually distinguished in some way) so you know you won't see any more results if you do click it?
Exactly.
Changing to an unrecognizable link color (such as grey), would introduce user experience (UX) complexity and confusion. We should avoid any inconvenience of parsing (or hovering over) the text to determine if certain grey words are still a link that still is clickable.
If you're looking for an alternative link color, purple might be a better choice (since it is more likely to still be recognizable as a visited link).
That would be a good choice.
