• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky lang ha hoi. hieu ((va cam) or (va cham)) ((luc va) OR (loc va)) dung tai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang ha hoi. hieu ((va cam) OR (va cham)) ((luc va) OR (loc va)) dung tai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang ha hoi. hieu ((va cam) or (va cham)) ((luc va) OR (loc va)) dung tai cau treo".
• Adding a wildcard symbol may retrieve word variants: tu sac ky lang ha hoi. hieu ((va cam) or (va cham)) ((luc va) OR (loc va)) dung tai cau treo*.
