Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets"
"yong yong li snippets" » "cong dong li snippets", "cong cong li snippets", "tong cong li snippets", "yong cong li snippets", "yong hong li snippets", "yong yang li 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 ("yong yong li snippets"))) OR ("locating bug core snippets"))~.
• Removing quotes may allow a broader search: (((( using java code snippets ) or ( yong yong li snippets ))) or ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") or ("yong yong li snippets"))) or ("locating bug core snippets"))*.
