Add specification from a loop

In a spring boot 3 application I try to use specification

public Page<User> advancedSearch(UserSearch search, Pageable page) {

      String[] splittedValues = search.name.split(" ");
    

      Specification<User> hasPersonWithName = (Root<User> root, CriteriaQuery<?> cq, CriteriaBuilder cb) -> {

            ...

            return pre;
        };

    return findAll(specification, page);

}

I need for every value in splittedValues to add a global specification

for (String splittedName: splittedValues) {
   specification.or(splittedName);
}

and pass it to findAll

I don't understand how to do it

Edit

you solution seem to work but

that generate

where
    1=1 
    or like e1_0.name "%bob%"
    or like e1_0.name "%jame%"

It's there a way to get

where
    1=1 
    and (
    like e1_0.name "%bob%"
    or like e1_0.name "%jame%"
    )

Using or operator , you combine multiple conditions, checking whether the name of User contains one of the splittedValues. Predicate is then returned from specification.

I hope that was what you wanted, in case I didn't understand, please correct me. Here is an example if so, adapt to your own code.

Edit: To get 1=1 and (like e1_0.name "%bob%" or like e1_0.name "%jame%"), you can use cb.or method to combine the conditions, resulting nameConditions is then combined with pre using cb.and.

public Page<User> advancedSearch(UserSearch search, Pageable page) {
    String[] splittedValues = search.name.split(" ");

    Specification<User> hasPersonWithName = (Root<User> root, CriteriaQuery<?> cq, CriteriaBuilder cb) -> {
        Predicate pre = cb.conjunction();
        Predicate nameConditions = null;
        for (String splittedName: splittedValues) {
            if (nameConditions == null) {
                nameConditions = cb.like(root.get("name"), "%" + splittedName + "%");
            } else {
                nameConditions = cb.or(nameConditions, cb.like(root.get("name"), "%" + splittedName + "%"));
            }
        }
        if (nameConditions != null) {
            pre = cb.and(pre, nameConditions);
        }
        return pre;
    };

return findAll(hasPersonWithName, page);
}
