Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java grippers" » "python using data grippers", "python using java slippers"
"nhe cac van snippets" » "he cac van snippets", "nghe cao van snippets", "nghe cnc van snippets", "nhe cac dan snippets"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("python using java grippers") OR ("nhe cac van snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using java grippers\") OR (\"nhe cac van snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( python using java grippers ) OR ( nhe cac van snippets ))) OR ( locating bug core snippets ))*.
