• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"thep van lam trinh doc.\") OR (\"thep xanh lap trinh doc.\"))) OR (\"thuc hanh lam dinh cac.\"))~".
• Removing quotes may allow a broader search: (((( thep van lam trinh doc. ) OR ( thep xanh lap trinh doc. ))) OR ( thuc hanh lam dinh cac. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thep van lam trinh doc.") OR ("thep xanh lap trinh doc."))) OR ("thuc hanh lam dinh cac."))*.
