• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ki nang van hoi. lieu va ((cam tuc) OR (cam tu)) va kinh ((vi cuu) OR (vi luu)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ki nang van hoi. lieu va ((cam tuc) OR (cam tu)) va kinh ((vi cuu) or (vi luu)) tre".
• Adding a wildcard symbol may retrieve word variants: su sach ki nang van hoi. lieu va ((cam tuc) OR (cam tu)) va kinh ((vi cuu) or (vi luu)) tre*.
