Perhaps you should try some spelling variations:
"python using code snippets" » "python using cfd snippets", "python using one snippets", "python using code slippers"
"phan co dat snippets" » "phan bo dat snippets", "phan cong dat snippets", "phan cac dat snippets", "phan coc dat snippets", "phan co dan snippets", "phan co dot snippets", "phan co 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: "((((\"phan co dat snippets\") OR (\"python using code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( phan co dat snippets ) OR ( python using code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("phan co dat snippets") OR ("python using code snippets"))) OR ("locating bug code snippets"))*.
