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 nhi van snippets" » "tri nho van snippets", "tri noi van snippets", "tri chi van snippets", "tri nhin van snippets", "tri thi van snippets", "tri nha van snippets", "tri nhi van 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 nhi van snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using raw snippets ) OR ( tri nhi van snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using raw snippets") OR ("tri nhi van snippets"))) OR ("locating bug code snippets"))*.
