Perhaps you should try some spelling variations:
"quintero sanchez." » "montero sanchez.", "guerrero sanchez.", "olivero sanchez."
"sainero sanchez." » "glicerio sanchez.", "calderon sanchez."
"gomez sanchez." » "lopez sanchez.", "perez sanchez.", "gonzalez sanchez."
"quieren saber." » "quiere saber.", "quiero saber.", "quieren ser."

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

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