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