Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets", "using java core snippets"
"trinh nha mo snippets" » "trinh phan mo snippets", "trinh chat mo snippets", "trinh chao mo snippets", "trinh nha moi snippets", "trinh nhan mo snippets", "trinh nha o 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 (\"trinh nha mo snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( trinh nha mo snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("trinh nha mo snippets"))) OR ("locating bug code snippets"))*.
