• If you are trying to use Boolean operators, they must be ALL CAPS: (((("te sach han quan ly") OR ("hoc cuc hai quan ly"))) OR ((((((("doc sach phap quang d") OR ("doc sach phap quan d"))) OR ("nuoc sach phap quang d"))) OR ("toc sach chat quang d"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"te sach han quan ly\") or (\"hoc cuc hai quan ly\"))) or (((((((\"doc sach phap quang d\") OR (\"doc sach phap quan d\"))) or (\"nuoc sach phap quang d\"))) or (\"toc sach chat quang d\"))))~".
• Removing quotes may allow a broader search: (((( te sach han quan ly ) or ( hoc cuc hai quan ly ))) or ((((((( doc sach phap quang d ) OR ( doc sach phap quan d ))) or ( nuoc sach phap quang d ))) or ( toc sach chat quang d ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("te sach han quan ly") or ("hoc cuc hai quan ly"))) or ((((((("doc sach phap quang d") OR ("doc sach phap quan d"))) or ("nuoc sach phap quang d"))) or ("toc sach chat quang d"))))*.
