• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sach ly) or (sach lo)) nang xa hoi. hieu ve ((cac xuc) OR (cac nuoc)) va danh dieu cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach ly) OR (sach lo)) nang xa hoi. hieu ve ((cac xuc) OR (cac nuoc)) va danh dieu cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach ly) or (sach lo)) nang xa hoi. hieu ve ((cac xuc) OR (cac nuoc)) va danh dieu cua tre".
• Adding a wildcard symbol may retrieve word variants: vu ((sach ly) or (sach lo)) nang xa hoi. hieu ve ((cac xuc) OR (cac nuoc)) va danh dieu cua tre*.
