JPA Specification - search simultaneously in main table rows and child rows with relation OneToMany - spring-boot

Question

I have two entities. One of them is a child of the other one with a relation with OneToMany. Is it possible to implement search criteria that looks up simultaneously in both the main entity and all the child entities?
Example: I have a Company with many employees. If I search with some text, I want to retrieve all the companies, which title contains that text or its employee's names contain that text.
Here are the example entities:
#Entity
public class Company extends AbstractEntity {
#Column(nullable = false, unique = true)
private String uuid;
#Column(nullable = false)
private String companyName;
#OneToMany(mappedBy = “company”, cascade = CascadeType.ALL, fetch = FetchType.EAGER, orphanRemoval = true)
protected Set<Employee> employees = new HashSet<>();
}
#Entity
public class Employee extends AbstractEntity {
#Column(nullable = false, unique = true)
private String uuid;
#Column(nullable = false)
private String firstName;
#Column(nullable = false)
private String lastName;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = “company_id”, nullable = false)
#OnDelete(action = OnDeleteAction.CASCADE)
private Company company;
}
Here is the example query, that I want to transform into Specification criteria
#Query(value = “SELECT DISTINCT c from Company c left outer join c.employees e
WHERE c.companyName LIKE CONCAT('%',:text,'%')
or e.firstName LIKE CONCAT('%',:text,'%')
or e.lastName LIKE CONCAT('%',:text,'%')”)

Answer 1

If you are using Spring JPA data repository, your interface method would look like this.
Company findByCompanyNameConatainingOrEmployeesFirstNameConatainingOrEmployeeslastNameConataining(String searchTextCompanyTitle, String searchTextEmployeeFName, String searchTextEmployeeLName);
If you are not using data repository, please explain your data access design to get an accurate answer.
