• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach lo) OR (sach dao)) lang van hoi. hieu vu cham xuc va ((hanh van) or (hanh va)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach lo) OR (sach dao)) lang van hoi. hieu vu cham xuc va ((hanh van) OR (hanh va)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach lo) OR (sach dao)) lang van hoi. hieu vu cham xuc va ((hanh van) or (hanh va)) cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach lo) OR (sach dao)) lang van hoi. hieu vu cham xuc va ((hanh van) or (hanh va)) cuu tre*.
