• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach tu) OR (sach thu)) ((nang xa) or (lang xa)) hoi. hieu van cam luc van thanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach tu) OR (sach thu)) ((nang xa) OR (lang xa)) hoi. hieu van cam luc van thanh vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach tu) OR (sach thu)) ((nang xa) or (lang xa)) hoi. hieu van cam luc van thanh vi cuu tre*".
