Perhaps you should try some spelling variations:
"python using java grippers" » "python using data grippers"
"_ mach a slippers" » "_ mac a slippers", "_ manh a slippers", "_ marche a slippers", "_ mach _ slippers", "_ mach o slippers", "_ mach cua slippers", "_ mach a 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 grippers\") OR (\"_ mach a slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java grippers ) OR ( _ mach a slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java grippers") OR ("_ mach a slippers"))) OR ("locating bug code snippets"))*.
