Perhaps you should try some spelling variations:
"python using data grippers" » "python using java grippers", "python using sat grippers", "python missing data grippers"
"_ le viet slippers" » "_ te viet slippers", "_ le viet slippery"
"locating bug code snippets" » "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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ le viet slippers") OR ("python using data grippers"))) OR ("locating bug code snippets"))~.
• Removing quotes may allow a broader search: (((( _ le viet slippers ) or ( python using data grippers ))) or ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ le viet slippers") or ("python using data grippers"))) or ("locating bug code snippets"))*.
