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 de doi snippets" » "dung he doi snippets", "dung dat doi snippets", "dung te doi snippets", "dung ve doi snippets", "dung ke doi 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 de doi snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm code snippets ) OR ( dung de doi snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm code snippets") OR ("dung de doi snippets"))) OR ("locating bugs code snippets"))*.
