This is a short survey on the star partial order for matrices which is considered in the spaces with indefinite metric.
The specific geometry of these spaces effects even on the definition of a star partial order, demanding the existence of the Moore--Penrose inverse of a certain matrix.
A characterization of this partial order is also given.
Some of the interesting properties are generalized and illustrated by the appropriate examples.
