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