• Performing a fuzzy search may retrieve terms with similar spellings: (((("ngo ngang truong") or ("ngoc dang truong"))) or ((("hao quang trung") OR ("ha quang trung"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ngo ngang truong") OR ("ngoc dang truong"))) OR ((("hao quang trung") OR ("ha quang trung")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ngo ngang truong\") or (\"ngoc dang truong\"))) or (((\"hao quang trung\") OR (\"ha quang trung\"))))".
• Removing quotes may allow a broader search: (((( ngo ngang truong ) or ( ngoc dang truong ))) or ((( hao quang trung ) OR ( ha quang trung )))).
• Adding a wildcard symbol may retrieve word variants: (((("ngo ngang truong") or ("ngoc dang truong"))) or ((("hao quang trung") OR ("ha quang trung"))))*.
