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 danh do snippets" » "dung doanh do snippets", "dung dan do snippets", "dung dang do snippets", "dung danh co snippets", "dung danh di 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 danh do snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm code snippets ) OR ( dung danh do snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm code snippets") OR ("dung danh do snippets"))) OR ("locating bugs code snippets"))*.
