unexpected query result

[Hilaire Fernandes]

I have this unexpected result from a MagmaSet query, where id is an 
Integer index:

(learners where: [:l | l id > 103654912]) size
=>2

(learners where: [:l | l id >= 103654912]) size
=>3

(learners where: [:l | l id = 103654912]) size
=>0

Also I am sure object with id = 103654912 is in the MagmaSet.

Index problem?
