Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets"
"hoan can cau snippets" » "toan can cau snippets", "hoang van cau snippets", "hoang cao cau snippets", "hoan van cau snippets", "hoan ban cau snippets", "hoan ca cau snippets"
"locating bug core snippets" » "locating bug code snippets"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("using java code snippets") OR ("hoan can cau snippets"))) OR ("locating bug core snippets"))~.
• Removing quotes may allow a broader search: (((( using java code snippets ) or ( hoan can cau snippets ))) or ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") or ("hoan can cau snippets"))) or ("locating bug core snippets"))*.
