Perhaps you should try some spelling variations:
"using ibm code snippets" » "using rbf code snippets", "using lbm code snippets", "using ibm code slippers"
"dung tu trinh snippets" » "dung tu tinh snippets", "dung tieu trinh snippets", "dung qua trinh snippets", "dung thu trinh snippets", "dung tru trinh snippets", "dung cu trinh snippets", "dung tu trinh 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 tu trinh snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm code snippets ) OR ( dung tu trinh snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm code snippets") OR ("dung tu trinh snippets"))) OR ("locating bug code snippets"))*.
