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