Can someone explain how to define multi column indexes in Grails? The documentation is at best sparse.

This for example does not seem to work at all: http://grails.org/GORM+Index+definitions

I've had some luck with this, but the results seems random at best. Definitions that works in one domain class does not when applied to another (with different names of course). http://www.grails.org/doc/1.1/guide/single.html#5.5.2.6%20Database%20Indices

Some working examples and explanations would be highly appreciated!
