• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach v) OR (sach xa)) nang xa hoi. ((hieu va) OR (lieu va)) tham nuoc va danh lien cuc te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach v) or (sach xa)) nang xa hoi. ((hieu va) OR (lieu va)) tham nuoc va danh lien cuc te".
• Adding a wildcard symbol may retrieve word variants: te ((sach v) or (sach xa)) nang xa hoi. ((hieu va) OR (lieu va)) tham nuoc va danh lien cuc te*.
