How use Hibernate Criteria with searching in Postgresql JSON and use with Lateral

On the client side we have endpoint for searching with filter.

On backend I have method for searching in Postgresql DB. One of the option - search into jsonb field.

Before this day I searched over values and keys. And my code was:

if (appFilter.getSearchValue() != null) {
    criteria.add(Restrictions.sqlRestriction("UPPER(values::text) LIKE '%" + appFilter.getSearchValue().toUpperCase() + "%'"));
}

SQL analog (UPPER - is not mandatory):

SELECT *
FROM application
WHERE UPPER(values :: TEXT) LIKE '%some text%'

Now I need search only into values. SQL query for this purpouse:

SELECT *
FROM application, LATERAL json_each_text(application.values :: JSON)
WHERE value :: TEXT LIKE '%some text%';

How I can add this into restrictions? Maybe there ara any another variants for searching into values? Hibernate 5.0.12

Restrictions.sqlRestriction will be insert in generated sql after WHERE clause with AND so you need add something like this 

criteria.add(Restrictions.sqlRestriction("this_.id IN (SELECT application.id FROM application , LATERAL json_each_text(values :: JSON) WHERE UPPER(value :: TEXT) LIKE '%" + appFilter.getSearchValue().toUpperCase() +"%')"));
