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