Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets"
"dung hoc quan snippets" » "dong hoc quan snippets", "dung thuoc quan snippets", "trung hoc quan snippets", "dung hoc dan snippets", "dung tac quan snippets", "dung hoc phan snippets"
"locating bug core snippets" » "locating bug 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 (\"dung hoc quan snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dung hoc quan snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dung hoc quan snippets"))) OR ("locating bug core snippets"))*.
