Hibernate Criteria AND OR operation on multiple where

This is your actual query, slightly more succint.

   session.createCriteria(EUser.class)
   .add(Restrictions.disjunction()
      .add(Restrictions.like("userName", "mat%"))
      .add(Restrictions.like("firstName", "mat%")) 
      .add(Restrictions.like("lastName", "mat%")) 
      .add(Restrictions.like("middleName", "mat%")))
   .add(Restrictions.eq("enable ", "active"))
   .list();

Rather wordy, but does keep your code nice an oop and easy to do dynamic and generic queries.
