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