Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"nha do van grippers" » "nha o van grippers", "nha da van grippers", "nha co van grippers", "nha dao van grippers", "nha vo van grippers", "nha so van grippers", "nha do van 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: "((((\"python using java snippets\") OR (\"nha do van grippers\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( nha do van grippers ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("nha do van grippers"))) OR ("locating bug core snippets"))*.
