• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ((tu nang) OR (tu nong)) ma hoi. hieu ve cham suc manh ((hanh vai) or (hanh tai)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((tu nang) OR (tu nong)) ma hoi. hieu ve cham suc manh ((hanh vai) OR (hanh tai)) cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((tu nang) OR (tu nong)) ma hoi. hieu ve cham suc manh ((hanh vai) or (hanh tai)) cuu tre*".
