Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets", "using java core snippets", "using java code slippers"
"dung su tam snippets" » "dung cu tam snippets", "dung du tam snippets", "dung so tam snippets", "dung suu tam snippets", "dung su tai snippets", "dung su nam snippets", "dung su tam slippers"
"locating bug code snippets" » "locating bug core 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 java code snippets\") OR (\"dung su tam snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dung su tam snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dung su tam snippets"))) OR ("locating bug code snippets"))*.
