• If you are trying to use Boolean operators, they must be ALL CAPS: coleccion practicas de ((y academico) OR (((lo academico) OR (del academico)))) excmo e cirugia.~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "coleccion practicas de ((y academico) or (((lo academico) OR (del academico)))) excmo e cirugia.~".
• Adding a wildcard symbol may retrieve word variants: coleccion practicas de ((y academico) or (((lo academico) OR (del academico)))) excmo e cirugia.*.
