Perhaps you should try some spelling variations:
"python using java slippery" » "python using data slippery", "python using java slippers"
"phap cau o grippers" » "phap cau soft grippers", "phan cau o grippers", "pha cau o grippers", "phap ca o grippers", "phap cau do grippers", "phap cau _ grippers"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core snippets", "locating bug code slippers"

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 slippery\") OR (\"phap cau o grippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java slippery ) OR ( phap cau o grippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippery") OR ("phap cau o grippers"))) OR ("locating bug code snippets"))*.
