Perhaps you should try some spelling variations:
"pha co so grippers" » "pha co soft grippers", "phan co so grippers", "phai co so grippers", "pa co so grippers"
"python using java slippers" » "python using data slippers", "python using java 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using java slippers\") OR (\"pha co so grippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java slippers ) OR ( pha co so grippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippers") OR ("pha co so grippers"))) OR ("locating bug code snippets"))*.
