Research behind this Forum topic:

Searched "geographic search" – saw this result
First link required me to login, then showed "page doesn't exist"
Second link mentions geographic search
...and links here:
https://help.evernote.com/hc/en-us/articles/360040282613-Search-overview - which does not: (no variations on 'lat' and 'long' either)
Third link goes here
...which is kinda pointless as it simply sends me here -
Which is the only reference.
There are no results for searches for "latitude" or "longitude" or variations.
