Perhaps you should try some spelling variations:
"using ibm code snippets" » "using rbf code snippets", "using lbm code snippets", "using ibm code slippers"
"van hanh code snippets" » "van hanh de snippets", "van hanh cong snippets", "van hanh cad snippets", "van thanh code snippets", "ban hanh code snippets", "van anh code snippets", "van hanh code 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 (\"van hanh code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm code snippets ) OR ( van hanh code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm code snippets") OR ("van hanh code snippets"))) OR ("locating bug code snippets"))*.
