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"
"van anh data snippets" » "van anh dat snippets", "van a data snippets", "van anh ta snippets", "van thanh data snippets", "van minh data snippets", "tuan anh data snippets", "van anh data 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 (\"van anh data snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( van anh data snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("van anh data snippets"))) OR ("locating bugs code snippets"))*.
