Perhaps you should try some spelling variations:
coleccion practicas » coleccion practica, coleccion didactica, coleccion actas
del academico » ano academico
lo academico » los academicos, ano academico, _ academic
y academico » y academicos, y academica, un academico
sr cirugia » por cirugia, en cirugia, de cirugia

You may be able to get more results by adjusting your search query.

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