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