Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets", "using java core snippets", "using java code slippers"
"qua dinh dat snippets" » "qua kinh dat snippets", "quy dinh dat snippets", "qua danh dat snippets", "qua dinh ket snippets", "qua dinh van snippets", "qua dinh lam snippets", "qua dinh dat slippers"
"locating bug code snippets" » "locating bug core snippets", "locating bug code slippers", "locating bung code snippets", "locating bugs code 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 (\"qua dinh dat snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( qua dinh dat snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("qua dinh dat snippets"))) OR ("locating bug code snippets"))*.
