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"
"va trang va snippets" » "va trung va snippets", "va thanh va snippets", "va nang va snippets", "va tran van snippets", "va hang va snippets", "va trang va slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core 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: "((((\"va trang va snippets\") OR (\"using raw java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( va trang va snippets ) OR ( using raw java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("va trang va snippets") OR ("using raw java snippets"))) OR ("locating bug code snippets"))*.
