Perhaps you should try some spelling variations:
"quintero sanchez." » "sainero sanchez.", "guerrero sanchez.", "olivero sanchez."
"montero sanchez." » "moreno sanchez.", "ollero sanchez.", "romero sanchez."
"quieren saber." » "quiero saber.", "quieren ser.", "quieres ser."
"quiere saber." » "quiero saber.", "quiere salir.", "quiere ser."

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("quiere saber.") or ("quieren saber."))) or ((("quintero sanchez.") OR ("montero sanchez."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("quiere saber.") OR ("quieren saber."))) OR ((("quintero sanchez.") OR ("montero sanchez.")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"quiere saber.\") or (\"quieren saber.\"))) or (((\"quintero sanchez.\") OR (\"montero sanchez.\"))))".
• Removing quotes may allow a broader search: (((( quiere saber. ) or ( quieren saber. ))) or ((( quintero sanchez. ) OR ( montero sanchez. )))).
• Adding a wildcard symbol may retrieve word variants: (((("quiere saber.") or ("quieren saber."))) or ((("quintero sanchez.") OR ("montero sanchez."))))*.
