• Performing a fuzzy search may retrieve terms with similar spellings: nhung thi ((((quan van) OR (quan va))) or (quy van)). noi ((dung quoc) or (dang quoc)) lo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nhung thi ((((quan van) OR (quan va))) OR (quy van)). noi ((dung quoc) OR (dang quoc)) lo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nhung thi ((((quan van) OR (quan va))) or (quy van)). noi ((dung quoc) or (dang quoc)) lo".
• Adding a wildcard symbol may retrieve word variants: nhung thi ((((quan van) OR (quan va))) or (quy van)). noi ((dung quoc) or (dang quoc)) lo*.
