Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets", "python using raw slippers"
"tri nha dan snippets" » "tri nhan dan snippets", "trai nha dan snippets", "tri nho dan snippets", "tri nhac dan snippets", "tri nha van snippets", "tri nha dan slippers"

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 nha dan snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using raw snippets ) OR ( tri nha dan snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using raw snippets") OR ("tri nha dan snippets"))) OR ("locating bugs code snippets"))*.
