Perhaps you should try some spelling variations:
"using ibm code snippets" » "using rbf code snippets", "using lbm code snippets", "using ibm code slippers"
"dung san tu snippets" » "dong san tu snippets", "dung sai tu snippets", "dung luan tu snippets", "dung san thu snippets", "dung sang tu snippets", "dung ban tu snippets", "dung san tu 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 san tu snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm code snippets ) OR ( dung san tu snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm code snippets") OR ("dung san tu snippets"))) OR ("locating bug code snippets"))*.
