• Performing a fuzzy search may retrieve terms with similar spellings: vu sach tham ((lang xa) or (dang xay)) hoi. hieu ((ve cham) OR (va cham)) tuc va hanh thoi cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach tham ((lang xa) OR (dang xay)) hoi. hieu ((ve cham) OR (va cham)) tuc va hanh thoi cua vat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach tham ((lang xa) or (dang xay)) hoi. hieu ((ve cham) OR (va cham)) tuc va hanh thoi cua vat".
• Adding a wildcard symbol may retrieve word variants: vu sach tham ((lang xa) or (dang xay)) hoi. hieu ((ve cham) OR (va cham)) tuc va hanh thoi cua vat*.
