• Performing a fuzzy search may retrieve terms with similar spellings: su sach v nang x hoi. lieu va cham ((xuc ban) OR (duc ban)) danh ((de cua) or (dieu cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach v nang x hoi. lieu va cham ((xuc ban) OR (duc ban)) danh ((de cua) OR (dieu cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach v nang x hoi. lieu va cham ((xuc ban) OR (duc ban)) danh ((de cua) or (dieu cua)) tre*".
