Perhaps you should try some spelling variations:
"using data java snippets" » "using java java snippets", "using sat java snippets", "missing data java snippets", "using data java slippers"
"vat dung code snippets" » "vat dung cong snippets", "vat dung co snippets", "vat dung de snippets", "van dung code snippets", "va dung code snippets", "viet dung code snippets", "vat dung code 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: "((((\"vat dung code snippets\") OR (\"using data java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( vat dung code snippets ) OR ( using data java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vat dung code snippets") OR ("using data java snippets"))) OR ("locating bug code snippets"))*.
