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"
"phan cong hai snippets" » "thanh cong hai snippets", "phan cong thai snippets", "phan cong ha snippets", "phan hoang hai snippets", "phan cong hai slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core 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 data java snippets\") OR (\"phan cong hai snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using data java snippets ) OR ( phan cong hai snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using data java snippets") OR ("phan cong hai snippets"))) OR ("locating bug code snippets"))*.
