Perhaps you should try some spelling variations:
"dau va dat grippers" » "dau va soft grippers", "dau ve dat grippers", "cau va dat grippers", "lau va dat grippers", "dau va dao grippers", "dau va dau grippers", "dau va dap grippers"
"python using java slippery" » "python using data slippery", "python using java 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: "((((\"dau va dat grippers\") OR (\"python using java slippery\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dau va dat grippers ) OR ( python using java slippery ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dau va dat grippers") OR ("python using java slippery"))) OR ("locating bug code snippets"))*.
