Perhaps you should try some spelling variations:
"using ibm code snippets" » "using rbf code snippets", "using lbm code snippets", "using ibm code slippers"
"dong anh thuc snippets" » "hong anh thuc snippets", "dong thanh thuc snippets", "hoang anh thuc snippets", "dong am thuc snippets", "dong dan thuc snippets", "dong anh tu snippets", "dong anh thuc 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 (\"dong anh thuc snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm code snippets ) OR ( dong anh thuc snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm code snippets") OR ("dong anh thuc snippets"))) OR ("locating bug code snippets"))*.
