• If you are trying to use Boolean operators, they must be ALL CAPS: (((("cong trinh chao dang va cac cay cot soi viet nam") OR ((("cong trinh co dang vant cac cay cot hoi viet nam") OR ("cong trinh co dang van cau cay cot hoi viet nam"))))) OR ((("cong trinh do hong va cau cay coc doi viet nam") OR ("cong trinh do luong va cau cay cot doi viet nam"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"cong trinh chao dang va cac cay cot soi viet nam\") or (((\"cong trinh co dang vant cac cay cot hoi viet nam\") OR (\"cong trinh co dang van cau cay cot hoi viet nam\"))))) or (((\"cong trinh do hong va cau cay coc doi viet nam\") or (\"cong trinh do luong va cau cay cot doi viet nam\"))))~".
• Removing quotes may allow a broader search: (((( cong trinh chao dang va cac cay cot soi viet nam ) or ((( cong trinh co dang vant cac cay cot hoi viet nam ) OR ( cong trinh co dang van cau cay cot hoi viet nam ))))) or ((( cong trinh do hong va cau cay coc doi viet nam ) or ( cong trinh do luong va cau cay cot doi viet nam ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("cong trinh chao dang va cac cay cot soi viet nam") or ((("cong trinh co dang vant cac cay cot hoi viet nam") OR ("cong trinh co dang van cau cay cot hoi viet nam"))))) or ((("cong trinh do hong va cau cay coc doi viet nam") or ("cong trinh do luong va cau cay cot doi viet nam"))))*.
