Perhaps you should try some spelling variations:
"dai luong code snippets" » "dai luong cong snippets", "dai luong che snippets", "dai cuong code snippets", "dai duong code snippets", "do luong code snippets"
"using raw java snippets" » "using real java snippets", "using a java snippets", "using low java 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 raw java snippets\") OR (\"dai luong code snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using raw java snippets ) OR ( dai luong code snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using raw java snippets") OR ("dai luong code snippets"))) OR ("locating bug core snippets"))*.
