(Quick Reference)
                where
Purpose
Defines a new 
grails.gorm.DetachedCriteria instance that uses a disjunction (logical OR).
Examples
Basic query:
def query = Person.whereAny {
   firstName == "Bart"
   firstName == "Lisa"   
}
Person bart = query.find()Description
The 
where method defaults to a conjunction (logical AND) for the created query. The 
whereAny compliments the 
where method by allowing the creation of 
DetachedCriteria using a disjunction (logical OR).
For more information on using the 
where method see the dedicated section on 
Where Queries and 
Detached Criteria in the user guide.
