• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ((ty dang) OR (ty xang)) xay hoi. hieu va cham ((xuc va) or (tuc va)) thanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ((ty dang) OR (ty xang)) xay hoi. hieu va cham ((xuc va) OR (tuc va)) thanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ((ty dang) OR (ty xang)) xay hoi. hieu va cham ((xuc va) or (tuc va)) thanh vi cua te*".
