Perhaps you should try some spelling variations:
"guerrero sanchez." » "herrero sanchez.", "herrera sanchez.", "guerrero mendez."
"olivero sanchez." » "ollero sanchez.", "glicerio sanchez.", "sainero 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 ((("olivero sanchez.") or ("guerrero sanchez."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("quiere saber.") OR ("quieren saber."))) OR ((("olivero sanchez.") OR ("guerrero sanchez."))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"quiere saber.\") OR (\"quieren saber.\"))) or (((\"olivero sanchez.\") or (\"guerrero sanchez.\"))))*".
• Removing quotes may allow a broader search: (((( quiere saber. ) OR ( quieren saber. ))) or ((( olivero sanchez. ) or ( guerrero sanchez. ))))*.
