consulta fix a sql con vectores

Buenas taardes lista , en esta consulta, implemento un vector en un OR
.pero al ejecutarla.. cuando busca por SSN osea un numero.. y es laprimera
parte del or. funciona bien .. pero cuando implemento la busqueda por
nombre que es la segunda parte del OR , obtengo resultado vacio. la consulta
no me devuelve nada..

Les consulto por si pueden mirarla. y decirme porque el vector no em esta
devolviendo valores.
GRacias.
