Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using data grippers" » "python using java grippers", "python using sat grippers", "python missing data grippers", "python using data slippers"
"thuc ve 07 snippets" » "thuc va 07 snippets", "thuc te 07 snippets", "thuc viet 07 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: "((((\"thuc ve 07 snippets\") OR (\"python using data grippers\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( thuc ve 07 snippets ) OR ( python using data grippers ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thuc ve 07 snippets") OR ("python using data grippers"))) OR ("locating bug core snippets"))*.
