Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets"
"lo bi trong snippets" » "lo ro trong snippets", "lo le trong snippets", "lo ly trong snippets", "so bi trong snippets"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("lo bi trong snippets") OR ("python using raw snippets"))) OR ("locating bug core snippets"))~.
• Removing quotes may allow a broader search: (((( lo bi trong snippets ) or ( python using raw snippets ))) or ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("lo bi trong snippets") or ("python using raw snippets"))) or ("locating bug core snippets"))*.
