Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using ibm code snippets" » "using rbf code snippets", "using lbm code snippets"
"dung dat vo snippets" » "dung va vo snippets", "dung tai vo snippets", "dung dat va snippets", "dung dat o snippets", "dung dat vi 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 dat vo snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm code snippets ) OR ( dung dat vo snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm code snippets") OR ("dung dat vo snippets"))) OR ("locating bugs code snippets"))*.
