Perhaps you should try some spelling variations:
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets", "python using raw slippers"
"tri hoc dat snippets" » "triet hoc dat snippets", "tri thuc dat snippets", "thai hoc dat snippets", "tri hoc dan snippets", "tri hoc dai snippets", "tri hoc phat snippets", "tri hoc dat slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core 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: "((((\"python using raw snippets\") OR (\"tri hoc dat snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using raw snippets ) OR ( tri hoc dat snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using raw snippets") OR ("tri hoc dat snippets"))) OR ("locating bug code snippets"))*.
