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