• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky nang x hoi. hieu va ((cac xuc) OR (cac nuoc)) va ((dhanh va) or (hanh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang x hoi. hieu va ((cac xuc) OR (cac nuoc)) va ((dhanh va) OR (hanh va)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang x hoi. hieu va ((cac xuc) OR (cac nuoc)) va ((dhanh va) or (hanh va)) cua tre".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang x hoi. hieu va ((cac xuc) OR (cac nuoc)) va ((dhanh va) or (hanh va)) cua tre*.
