Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using java code snippets" » "using data code snippets", "using java code slippers"
"tung dan dat snippets" » "dung dan dat snippets", "huong dan dat snippets", "trung dai dat snippets", "tung dung dat snippets", "tung dong dat snippets", "tung dinh dat snippets", "tung dan dat slippers"

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 (\"tung dan dat snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( tung dan dat snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("tung dan dat snippets"))) OR ("locating bugs code snippets"))*.
