Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"chu va dan snippets" » "chu van dan snippets", "chuc va dan snippets", "chua va dan snippets", "chu ca dan snippets", "chu va dao snippets", "chu va dau snippets", "chu va dan 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: "((((\"python using java snippets\") OR (\"chu va dan snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( chu va dan snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("chu va dan snippets"))) OR ("locating bug code snippets"))*.
