Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets", "using java core snippets", "using java code slippers"
"lua hoc dat snippets" » "luan hoc dat snippets", "luc hoc dat snippets", "cua hoc dat snippets", "lua hoc dan snippets", "lua hoc dai snippets", "lua hoc phat snippets", "lua hoc 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 (\"lua hoc dat snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( lua hoc dat snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("lua hoc dat snippets"))) OR ("locating bug code snippets"))*.
