Perhaps you should try some spelling variations:
"dung chung dat snippets" » "dung cong dat snippets", "dung trung dat snippets", "truong chung dat snippets", "dung chung bat snippets", "dung cung dat snippets", "dung dung dat snippets", "dung chung dat slippers"
"using ibm code snippets" » "using rbf code snippets", "using lbm code snippets", "using ibm code slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"using ibm code snippets\") OR (\"dung chung dat snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm code snippets ) OR ( dung chung dat snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm code snippets") OR ("dung chung dat snippets"))) OR ("locating bug code snippets"))*.
