Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets"
"dang cac nhat snippets" » "dung cac nhat snippets", "bang cac nhat snippets", "dong cac nhat snippets", "dang cac nha snippets", "dang cac nhan snippets", "dang cac chat snippets"
"locating bug core snippets" » "locating bug 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 (\"dang cac nhat snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dang cac nhat snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dang cac nhat snippets"))) OR ("locating bug core snippets"))*.
