• If you are trying to use Boolean operators, they must be ALL CAPS: ((done using) OR (doom using)) ya how best yan ((thi zhong) OR (thi phuong)) tai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((done using) or (doom using)) ya how best yan ((thi zhong) OR (thi phuong)) tai ;~".
• Adding a wildcard symbol may retrieve word variants: ((done using) or (doom using)) ya how best yan ((thi zhong) OR (thi phuong)) tai ;*.
