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"
"cong coc dat snippets" » "cong cuoc dat snippets", "cong cac dat snippets", "cong co dat snippets", "cong hoc dat snippets", "cong chon dat snippets", "cong duoc dat snippets", "cong coc 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 (\"cong coc dat snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( cong coc dat snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("cong coc dat snippets"))) OR ("locating bugs code snippets"))*.
