This topic has been discussed on the user mailing list.

The actual suggestion for a correct dynamic finder formular in the documentation is:

Book.findBy([Property][Comparator][Boolean Operator])?[Property][Comparator] (see http://grails.org/doc/1.0.x/guide/single.html#5.4.1%20Dynamic%20Finders "Method expressions" for the current state of the documentation.

Here is the link into the mail thread which contains the full discussion. http://www.nabble.com/Problem-with-more-than-two-parameters-in-dynamic-finders-to16517807.html#a16517807

Assigning all documentation related issues to 1.2 final since they don't represent a change to the codebase

Section 5.4.1 of the user guide currently says...

"At the moment, you can only use dynamic finders with a maximum of two criteria, i.e. the method name can only have one boolean operator."

I think this correctly describes the current implementation.
