docs: Adds a "like" constraint to a <i>persistent field</i>. This method
  requires a {@link MatchMode} to specify how wildcards are added
  to the value. You may also use {@link #like(String, String)} if you
  want to manually specify the wildcards in the match string.
  
  @param relativePath relative path of the field
  @param value the match string
  @param matchMode specifies how to add wildcards to the value to create
  the LIKE expression
  @return {@link Criterion} instance
