Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"tran anh java snippets" » "tran manh java snippets", "tuan anh java snippets", "tran thanh java snippets", "tran anh va snippets"
"python using c snippets" » "python using lc snippets", "python using a snippets", "python using _ 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: "((((\"python using c snippets\") OR (\"tran anh java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using c snippets ) OR ( tran anh java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using c snippets") OR ("tran anh java snippets"))) OR ("locating bugs code snippets"))*.
