Default gist index on cube column

Hi,
I had some doubts about the gist index on cube column. So if I have a
column of type cube and create a gist index on it, would the index be
on individual elements in the cube or the cube as a whole. I mean will
a gist index on cube column improve the performance of earthdistance
function or cube_distance function.

Thanks
Abhang

The index will work on any operators the index is defined to work on.
So I suggest looking at the documentation for what operators are
defined and whether they solve your problem.

Have a nice day,
