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