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