Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using ibm code snippets" » "using rbf code snippets", "using lbm code snippets", "using ibm code slippers"
"van bui code snippets" » "van bug code snippets", "van bui cong snippets", "van bui code slippers"

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 bui code snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm code snippets ) OR ( van bui code snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm code snippets") OR ("van bui code snippets"))) OR ("locating bugs code snippets"))*.
