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