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"
"nha so van snippets" » "nhat so van snippets", "nha o van snippets", "nha co van snippets", "nha su van snippets", "nha vo van 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 java grippers\") OR (\"nha so van snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java grippers ) OR ( nha so van snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java grippers") OR ("nha so van snippets"))) OR ("locating bug core snippets"))*.
