Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using raw code snippets" » "using real code snippets", "using a code snippets", "using low code snippets", "using rate code snippets", "using raw code slippers"
"dung va code snippets" » "dung va code slippers"

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 code snippets\") OR (\"dung va code snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using raw code snippets ) OR ( dung va code snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using raw code snippets") OR ("dung va code snippets"))) OR ("locating bugs code snippets"))*.
