Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using data grippers" » "python using java grippers", "python using sat grippers", "python missing data grippers", "python using data slippers"
"nhe cac dan snippets" » "he cac dan snippets", "nghe cao dan snippets", "nghe cnc dan 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 data grippers\") OR (\"nhe cac dan snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using data grippers ) OR ( nhe cac dan snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using data grippers") OR ("nhe cac dan snippets"))) OR ("locating bug core snippets"))*.
