Perhaps you should try some spelling variations:
uso medico » un medico, su medico
el medico » el medio, el mexico
y medicos » y medios, y medicion, de medicos
y medico » y medio, y mexico, y medica
onu y » ong y, one y
ou y » bou y, pou y, cu y
medianas.* » mediana.*, mediante.*, medicas.*

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((el medico) or (uso medico))) or (((y medico) or (y medicos)))), ((ou y) OR (onu y)) medianas.~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((el medico) OR (uso medico))) OR (((y medico) OR (y medicos)))), ((ou y) OR (onu y)) medianas.*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((el medico) or (uso medico))) or (((y medico) or (y medicos)))), ((ou y) OR (onu y)) medianas.*".
