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 cho snippets" » "tran manh cho snippets", "tuan anh cho snippets", "tran thanh cho snippets", "tran danh cho snippets", "tran anh tho snippets", "tran anh co 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 cho snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( tran anh cho snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("tran anh cho snippets"))) OR ("locating bugs code snippets"))*.
