Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using ibm code snippets" » "using rbf code snippets", "using lbm code snippets"
"dung nhan con snippets" » "dung luan con snippets", "dung nhan co snippets", "dung nhanh cong snippets", "dung phan cong 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 nhan con snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm code snippets ) OR ( dung nhan con snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm code snippets") OR ("dung nhan con snippets"))) OR ("locating bugs code snippets"))*.
