• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ty ((xang xa) OR (ang xa)) hoi. hieu van chat ((tuc va) or (tuc xa)) thanh doi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ty ((xang xa) OR (ang xa)) hoi. hieu van chat ((tuc va) OR (tuc xa)) thanh doi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ty ((xang xa) OR (ang xa)) hoi. hieu van chat ((tuc va) or (tuc xa)) thanh doi cua te".
• Adding a wildcard symbol may retrieve word variants: toc sach ty ((xang xa) OR (ang xa)) hoi. hieu van chat ((tuc va) or (tuc xa)) thanh doi cua te*.
