Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets", "using java core snippets"
"cung than cui snippets" » "cung thang cui snippets", "chung than cui snippets", "cung tan cui snippets", "cung than cua snippets", "cung than nui snippets", "cung thanh qui snippets"
"locating bug code snippets" » "locating bug core snippets", "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 (\"cung than cui snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( cung than cui snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("cung than cui snippets"))) OR ("locating bug code snippets"))*.
