• Performing a fuzzy search may retrieve terms with similar spellings: ((((tu sach) OR (su sach))) or (thuat sach)) ly nang xa hoi. hieu van hau phuc vu hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu sach) OR (su sach))) OR (thuat sach)) ly nang xa hoi. hieu van hau phuc vu hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tu sach) OR (su sach))) or (thuat sach)) ly nang xa hoi. hieu van hau phuc vu hanh vai cua tre*".
