Perhaps you should try some spelling variations:
"van cu dan grippers" » "van cau dan grippers", "van chu dan grippers", "van cua dan grippers", "van ca dan grippers", "van co dan grippers", "van cu dan slippers"
"python using a snippets" » "python using a slippers"
"locating bug code snippets" » "locating bug code slippers", "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 a snippets\") OR (\"van cu dan grippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using a snippets ) OR ( van cu dan grippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using a snippets") OR ("van cu dan grippers"))) OR ("locating bug code snippets"))*.
