Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"da van ruan snippets" » "da van quan snippets", "da van tuan snippets", "da van huan snippets", "dao van ruan snippets", "dam van ruan snippets", "va van ruan snippets", "da van ruan 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: "((((\"da van ruan snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( da van ruan snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("da van ruan snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
