Perhaps you should try some spelling variations:
"python using java grippers" » "python using data grippers", "python using java slippers"
"phan tu can slippery" » "phan tu ban slippery", "phan tu cac slippery", "phan thu canh slippery", "phan tu can slippers"
"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: "((((\"phan tu can slippery\") OR (\"python using java grippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( phan tu can slippery ) OR ( python using java grippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("phan tu can slippery") OR ("python using java grippers"))) OR ("locating bug code snippets"))*.
