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"
"thap muoi 3 snippets" » "hai muoi 3 snippets", "phap nuoi 3 snippets", "phap moi 3 snippets", "thap moi 3 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 (\"thap muoi 3 snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java grippers ) OR ( thap muoi 3 snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java grippers") OR ("thap muoi 3 snippets"))) OR ("locating bug core snippets"))*.
