• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach tu) OR (sach ty)) ((lang xa) or (lang van)) hoi. hieu van nam xuc va dau vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach tu) OR (sach ty)) ((lang xa) OR (lang van)) hoi. hieu van nam xuc va dau vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach tu) OR (sach ty)) ((lang xa) or (lang van)) hoi. hieu van nam xuc va dau vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach tu) OR (sach ty)) ((lang xa) or (lang van)) hoi. hieu van nam xuc va dau vai cuu tre*.
