• Performing a fuzzy search may retrieve terms with similar spellings: te sach y ((lang ha) or (dang xay)) hoi. hieu va chat xuc va ((hanh di) OR (hanh vi)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((lang ha) OR (dang xay)) hoi. hieu va chat xuc va ((hanh di) OR (hanh vi)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((lang ha) or (dang xay)) hoi. hieu va chat xuc va ((hanh di) OR (hanh vi)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y ((lang ha) or (dang xay)) hoi. hieu va chat xuc va ((hanh di) OR (hanh vi)) cua tre*.
