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"
"van hai va snippets" » "van ha va snippets", "van chat va snippets", "van hanh va snippets", "van hai van snippets", "van thai va snippets", "van hoi va snippets", "van hai 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: "((((\"van hai va snippets\") OR (\"using raw java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( van hai va snippets ) OR ( using raw java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("van hai va snippets") OR ("using raw java snippets"))) OR ("locating bug code snippets"))*.
