Perhaps you should try some spelling variations:
"using ibm code snippets" » "using rbf code snippets", "using lbm code snippets", "using ibm code slippers"
"dung ca tang snippets" » "dung cua tang snippets", "dung cac tang snippets", "dung cam tang snippets", "dung cao tang snippets", "dung ha tang snippets", "dung gia tang snippets", "dung ca tang 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 ca tang snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm code snippets ) OR ( dung ca tang snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm code snippets") OR ("dung ca tang snippets"))) OR ("locating bug code snippets"))*.
