Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"dan ba tran snippets" » "dan ban tran snippets", "dan bao tran snippets", "dan ba trao snippets", "dan bac tran snippets", "dan ca tran snippets", "dan va tran snippets", "dan ba tran 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 (\"dan ba tran snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( dan ba tran snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("dan ba tran snippets"))) OR ("locating bug code snippets"))*.
