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"
"phan dan dat snippets" » "phan dang dat snippets", "phan dau dat snippets", "nhan dan dat snippets", "phan dung dat snippets", "phan dong dat snippets", "phan dinh dat snippets", "phan dan dat 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 (\"phan dan dat snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( phan dan dat snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("phan dan dat snippets"))) OR ("locating bugs code snippets"))*.
