• Performing a fuzzy search may retrieve terms with similar spellings: (((("cong trinh da van va cac cay co loi viet nam") or ((("cong tinh cao lanh van cac cac co o viet nam") or ("cong vinh cao lanh van cac cac co so viet nam"))))) or ((((("cong trinh co tang van cac cau cong oi viet nam") OR ("cong trinh co tang van cau cau cong oi viet nam"))) or ("cong trinh ky tang van ca cay cong goi viet nam"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("cong trinh da van va cac cay co loi viet nam") OR ((("cong tinh cao lanh van cac cac co o viet nam") OR ("cong vinh cao lanh van cac cac co so viet nam"))))) OR ((((("cong trinh co tang van cac cau cong oi viet nam") OR ("cong trinh co tang van cau cau cong oi viet nam"))) OR ("cong trinh ky tang van ca cay cong goi viet nam")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"cong trinh da van va cac cay co loi viet nam\") or (((\"cong tinh cao lanh van cac cac co o viet nam\") or (\"cong vinh cao lanh van cac cac co so viet nam\"))))) or (((((\"cong trinh co tang van cac cau cong oi viet nam\") OR (\"cong trinh co tang van cau cau cong oi viet nam\"))) or (\"cong trinh ky tang van ca cay cong goi viet nam\"))))".
• Removing quotes may allow a broader search: (((( cong trinh da van va cac cay co loi viet nam ) or ((( cong tinh cao lanh van cac cac co o viet nam ) or ( cong vinh cao lanh van cac cac co so viet nam ))))) or ((((( cong trinh co tang van cac cau cong oi viet nam ) OR ( cong trinh co tang van cau cau cong oi viet nam ))) or ( cong trinh ky tang van ca cay cong goi viet nam )))).
• Adding a wildcard symbol may retrieve word variants: (((("cong trinh da van va cac cay co loi viet nam") or ((("cong tinh cao lanh van cac cac co o viet nam") or ("cong vinh cao lanh van cac cac co so viet nam"))))) or ((((("cong trinh co tang van cac cau cong oi viet nam") OR ("cong trinh co tang van cau cau cong oi viet nam"))) or ("cong trinh ky tang van ca cay cong goi viet nam"))))*.
