• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((v lang) OR (va lang)) xa hoi. hieu van ((chat truc) or (chat xuc)) va danh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((v lang) OR (va lang)) xa hoi. hieu van ((chat truc) OR (chat xuc)) va danh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((v lang) OR (va lang)) xa hoi. hieu van ((chat truc) or (chat xuc)) va danh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((v lang) OR (va lang)) xa hoi. hieu van ((chat truc) or (chat xuc)) va danh vi cua tre*.
