• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thieu hang xa hoi. hieu ((ve cam) or (va cam)) xuc va ((nhanh hai) OR (nhanh ha)) cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thieu hang xa hoi. hieu ((ve cam) OR (va cam)) xuc va ((nhanh hai) OR (nhanh ha)) cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thieu hang xa hoi. hieu ((ve cam) or (va cam)) xuc va ((nhanh hai) OR (nhanh ha)) cua viet".
• Adding a wildcard symbol may retrieve word variants: tu sach thieu hang xa hoi. hieu ((ve cam) or (va cam)) xuc va ((nhanh hai) OR (nhanh ha)) cua viet*.
