Perhaps you should try some spelling variations:
"python using java slippery" » "python using data slippery", "python using java slippers"
"ba quan den grippers" » "ba quan doan grippers", "ba quan he grippers", "ba quan doi grippers", "ban quan den grippers", "bao quan den grippers", "boa quan den grippers", "ba quan den 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: "((((\"ba quan den grippers\") OR (\"python using java slippery\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( ba quan den grippers ) OR ( python using java slippery ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ba quan den grippers") OR ("python using java slippery"))) OR ("locating bug code snippets"))*.
