Usually, "OR" operation is used to combine items from unstructured elements that look for different information patterns, for example, a single word of 10 digits may be detected as Registration number and ID number. "Unify" operation is used to combine iterms from unstructured elements that look for same information pattern. For example, In case of two unstrucetured regex elements that look for "mm\dd\yyyy" and "mmddyyyy" dates successively, the first regex element has error approximation value equals 2, and so, it can detect the second element's items if it does not have errors, this makes same "mmddyyyy" items to be duplicated and "Unify" operation is used to remove this duplication.
