• If you are trying to use Boolean operators, they must be ALL CAPS: (("lucan a investigacion") OR ((("lacan ma investigacion") OR ("lucan ma investigacion"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"lucan a investigacion\") or (((\"lacan ma investigacion\") OR (\"lucan ma investigacion\"))))*".
