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 cao dan snippets" » "tri co dan snippets", "tai cao dan snippets", "tri cac dan snippets", "tri cao dang snippets", "tri cao danh snippets", "tri cao 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 cao dan snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using raw snippets ) OR ( tri cao dan snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using raw snippets") OR ("tri cao dan snippets"))) OR ("locating bugs code snippets"))*.
