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