Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets", "using java core snippets"
"hung tran moi snippets" » "huong tran moi snippets", "quang tran moi snippets", "hung thang moi snippets", "hung tren moi snippets", "hung tran mai snippets", "hung tran mi snippets"
"locating bug code snippets" » "locating bug core 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 java code snippets\") OR (\"hung tran moi snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( hung tran moi snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("hung tran moi snippets"))) OR ("locating bug code snippets"))*.
