• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"van hoc thoi ky can trong.\") OR (\"van hoc thoi sy vien trong.\"))~".
• Removing quotes may allow a broader search: (( van hoc thoi ky can trong. ) OR ( van hoc thoi sy vien trong. ))~.
• Adding a wildcard symbol may retrieve word variants: (("van hoc thoi ky can trong.") OR ("van hoc thoi sy vien trong."))*.
