Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"dong cua doc snippets" » "dung cua doc snippets", "cong cua doc snippets", "huong cua doc snippets", "dong cua duoc snippets", "dong cua duc snippets", "dong cua hoc 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 (\"dong cua doc snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dong cua doc snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dong cua doc snippets"))) OR ("locating bugs code snippets"))*.
