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