• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"vi trong dao snippets\") OR (\"using low java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( vi trong dao snippets ) OR ( using low java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi trong dao snippets") OR ("using low java snippets"))) OR ("locating bugs code snippets"))*.
