Perhaps you should try some spelling variations:
"python using code snippets" » "python using cfd snippets", "python using one snippets", "python using code slippers"
"tan dan dat snippets" » "tang dan dat snippets", "tan doan dat snippets", "ban dan dat snippets", "tan dung dat snippets", "tan dong dat snippets", "tan dinh dat snippets", "tan dan dat slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code 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: "((((\"tan dan dat snippets\") OR (\"python using code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( tan dan dat snippets ) OR ( python using code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("tan dan dat snippets") OR ("python using code snippets"))) OR ("locating bug code snippets"))*.
