Perhaps you should try some spelling variations:
"using ibm code snippets" » "using rbf code snippets", "using lbm code snippets", "using ibm code slippers"
"luong cac dung snippets" » "luong cuoc dung snippets", "luong va dung snippets", "luong tai dung snippets", "luong cach dung snippets", "luong cac duong snippets", "luong tac dung snippets", "luong cac dung 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 (\"luong cac dung snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using ibm code snippets ) OR ( luong cac dung snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using ibm code snippets") OR ("luong cac dung snippets"))) OR ("locating bug code snippets"))*.
