• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ky) OR (sach ty)) nang mai hoi. hieu ((ve cham) or (ve chat)) cuu va hanh kem cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach ty)) nang mai hoi. hieu ((ve cham) OR (ve chat)) cuu va hanh kem cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sach ty)) nang mai hoi. hieu ((ve cham) or (ve chat)) cuu va hanh kem cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sach ty)) nang mai hoi. hieu ((ve cham) or (ve chat)) cuu va hanh kem cua tre*.
