Perhaps you should try some spelling variations:
"guerrero sanchez." » "herrero sanchez.", "herrera sanchez.", "guerrero mendez."
"olivero sanchez." » "ollero sanchez.", "glicerio sanchez.", "sainero sanchez."
"quiere saber." » "quieren saber.", "quiero saber.", "quiere ser."
"quiere salir." » "quieren saber.", "quiero saber.", "quiere ir."

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: (((("quiere saber.") OR ("quiere salir."))) OR ((("guerrero sanchez.") OR ("olivero sanchez."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"quiere saber.\") OR (\"quiere salir.\"))) or (((\"guerrero sanchez.\") or (\"olivero sanchez.\"))))~".
• Removing quotes may allow a broader search: (((( quiere saber. ) OR ( quiere salir. ))) or ((( guerrero sanchez. ) or ( olivero sanchez. ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("quiere saber.") OR ("quiere salir."))) or ((("guerrero sanchez.") or ("olivero sanchez."))))*.
