Perhaps you should try some spelling variations:
"using raw java snippets" » "using real java snippets", "using a java snippets", "using low java snippets", "using raw java slippers"
"vi dong code snippets" » "vi dong co snippets", "vi dong che snippets", "vi dong cong snippets", "voi dong code snippets", "di dong code snippets", "va dong code snippets", "vi dong code slippers"
"locating bug code snippets" » "locating bug code slippers", "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 raw java snippets\") OR (\"vi dong code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using raw java snippets ) OR ( vi dong code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using raw java snippets") OR ("vi dong code snippets"))) OR ("locating bug code snippets"))*.
