How to search using a domain class instance?

Question

I have a domain class User with all the instances like

[User : 1, User: 2, User : 3, User:4, User: 5, User: 6, User: 7, ...]

and an instance list userInstanceList with only a few objects, say

[User : 3, User:4]

My search term is in User : 4 and also in some other objects in User. When I search using

User.search(userInstanceList, searchTerm)

it returns all the objects in User with the searchTerm. How can I search objects only in userInstanceList

Answer 1

If you want to restrict the search to only the things in the userInstanceList, you should be able to just use the in clause when searching.

User.findAll { 
   searchTerm && id in userInstanceList*.id
}

or

User.withCriteria {
    searchTerm
    inList id, userInstanceList*.id
}
