Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using ibm code snippets" » "using rbf code snippets", "using lbm code snippets", "using ibm code slippers"
"dung danh duc snippets" » "dung doanh duc snippets", "dung dan duc snippets", "dung dang duc snippets", "dung anh duc snippets", "dung dinh duc snippets", "dung danh duc slippers"

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 danh duc snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm code snippets ) OR ( dung danh duc snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm code snippets") OR ("dung danh duc snippets"))) OR ("locating bugs code snippets"))*.
