Perhaps you should try some spelling variations:
"python using code snippets" » "python using cfd snippets", "python using one snippets"
"trinh ly co snippets" » "trinh ky co snippets", "trinh do co snippets", "trinh tu co snippets", "trinh ty co snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code 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: (((("trinh ly co snippets") OR ("python using code snippets"))) OR ("locating bug code snippets"))~.
• Removing quotes may allow a broader search: (((( trinh ly co snippets ) or ( python using code snippets ))) or ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trinh ly co snippets") or ("python using code snippets"))) or ("locating bug code snippets"))*.
