Perhaps you should try some spelling variations:
"using ibm core snippets" » "using rbf core snippets", "using lbm code snippets"
"dung rung code snippets" » "dung trung code snippets", "duong rung code snippets", "dung ung code snippets"
"locating bug code snippets" » "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 core snippets\") OR (\"dung rung code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm core snippets ) OR ( dung rung code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm core snippets") OR ("dung rung code snippets"))) OR ("locating bug code snippets"))*.
