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