Perhaps you should try some spelling variations:
"python using data grippers" » "python using java grippers", "python using sat grippers", "python missing data grippers", "python using data slippers"
"hoc dan so snippets" » "hoc dan soc snippets", "hoc dan su snippets", "hoc dan mo snippets"
"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: "((((\"hoc dan so snippets\") OR (\"python using data grippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( hoc dan so snippets ) OR ( python using data grippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hoc dan so snippets") OR ("python using data grippers"))) OR ("locating bug code snippets"))*.
