Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"de tao tran snippets" » "de tan tran snippets", "de bao tran snippets", "de tao trong snippets", "de dao tran snippets", "de tai tran snippets", "de tro tran snippets", "de tao 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 (\"de tao tran snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( de tao tran snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("de tao tran snippets"))) OR ("locating bug code snippets"))*.
