Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets"
"minh dan phan snippets" » "minh danh phan snippets", "minh doan phan snippets", "binh dan phan snippets", "minh dan chan snippets", "minh van phan snippets"
"locating bug core snippets" » "locating bug code snippets"

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

• Removing quotes may allow a broader search: (((( using java code snippets ) or ( minh dan phan snippets ))) or ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") or ("minh dan phan snippets"))) or ("locating bug core snippets"))*.
