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