@nknize please could you take a look

[nknize]

I'm on it...

[colings86]

It seems to be the point [0, 51.61536] which causes the issue, if this is changed to [0.001, 51.61536] the search correctly returns 0 hits. So it looks like the problem might be with polygons with points exactly on the GMT line

[zhaozhijun1988]

I also have the same issue， How to solve it;
