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