• If you are trying to use Boolean operators, they must be ALL CAPS: (((("hoang dung con snippets") OR ("hoang vuong con snippets"))) OR ("locating bug code snippets")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"hoang dung con snippets\") OR (\"hoang vuong con snippets\"))) or (\"locating bug code snippets\"))".
• Removing quotes may allow a broader search: (((( hoang dung con snippets ) OR ( hoang vuong con snippets ))) or ( locating bug code snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("hoang dung con snippets") OR ("hoang vuong con snippets"))) or ("locating bug code snippets"))*.
