(Quick Reference)
                findAllBy*
Purpose
Dynamic method that uses the properties of the domain class to create query method expressions that return all matching instances of the domain class
Examples
Given this domain class:
class Book {
    String title
    Date releaseDate
    String author
    Boolean paperback
}The following are all possible:
def results = Book.findAllByTitle("The Shining",
                  [max: 10, sort: "title", order: "desc", offset: 100])results = Book.findAllByTitleAndAuthor("The Sum of All Fears", "Tom Clancy")results = Book.findAllByReleaseDateBetween(firstDate, new Date())results = Book.findAllByReleaseDateGreaterThanEquals(firstDate)results = Book.findAllByTitleLike("%Hobbit%")results = Book.findAllByTitleIlike("%Hobbit%") // ignore caseresults = Book.findAllByTitleNotEqual("Harry Potter")results = Book.findAllByReleaseDateIsNull()results = Book.findAllByReleaseDateIsNotNull()results = Book.findAllPaperbackByAuthor("Douglas Adams")results = Book.findAllNotPaperbackByAuthor("Douglas Adams")results = Book.findAllByAuthorInList(["Douglas Adams", "Hunter S. Thompson"])Description
GORM supports the notion of 
Dynamic Finders. The 
findAllBy* method finds all the results for the given method expression.
Parameters:
- metaParams- A- Map containing pagination parameters- max,- order,- offsetand- sortand metaParameters- readOnly,- timeout,- fetchSize, and- flushMode
Pagination and sorting parameters can be used as the last argument to a dynamic method:
def results = Book.findAllByTitle("The Shining",
                 [max: 10, sort: "title", order: "desc", offset: 100])The following operator names can be used within the respective dynamic methods:
- LessThan
- LessThanEquals
- GreaterThan
- GreaterThanEquals
- Between
- Like
- Ilike(i.e. ignorecase like)
- IsNotNull
- IsNull
- Not
- NotEqual
- And
- Or
- InList
These operator names can be considered keywords, and you will run into problems when querying domain classes that have one of these names as property names. For more information on 
dynamic finders refer to the user guide.
