te sach » toc sach
lang xa » lang ha, lang van
ve pham » v pham, ve phan, ve phat
va tinh » may tinh

You may be able to get more results by adjusting your search query.

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