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