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." » "quiere saber.", "quiero saber.", "quieres ser."
"quieren ser." » "quieres ser.", "quiere ser.", "quieren serlo."

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

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