• Performing a fuzzy search may retrieve terms with similar spellings: tu san ((ky tang) OR (ky nang)) ma hoi. lieu va tham soc va thanh ((vi cuu) or (dinh cuu)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san ((ky tang) OR (ky nang)) ma hoi. lieu va tham soc va thanh ((vi cuu) OR (dinh cuu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ((ky tang) OR (ky nang)) ma hoi. lieu va tham soc va thanh ((vi cuu) or (dinh cuu)) tre".
• Adding a wildcard symbol may retrieve word variants: tu san ((ky tang) OR (ky nang)) ma hoi. lieu va tham soc va thanh ((vi cuu) or (dinh cuu)) tre*.
