How to use strtree to find an element nearest to it but not its own?

Expected behavior and actual behavior.

How to use strtree to find an element nearest to it but not its own?My code is as follows, what I expect to find is (1,1), not (0,0).
If I want to start from (0,0), find the nearest point (1,1), and then find the second nearest point (2,2), how do I operate?

Steps to reproduce the problem.

from shapely.strtree import STRtree
from shapely.geometry import Point

points=[Point(0,0),Point(1,1),Point(2,2)]

tree=STRtree(points)

pos=tree.nearest(Point(0,0))
print(pos)

#POINT (0 0)

Operating system

windows 10 20H2
python3.7.0 64-bit (conda)

Shapely version and provenance

Shapely-1.7.1 from pip install

I'm sorry to say @liunx7594 that the tree's nearest() method is behaving correctly here. However, I do have an idea for adding a new method to the STRtree API in version 1.8.0, one that would allow you to exclude the query geometry from the result. See #1094 .

OK, I'm looking forward to the next features

By the way, it's really a great library, and thank you so much for creating it
