Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using c snippets" » "python using lc snippets", "python using a snippets", "python using _ snippets"
"tri thi dan snippets" » "tri tai dan snippets", "tai thi dan snippets", "thi thi dan snippets", "tri thi doan snippets", "tri thi lan snippets", "tri thi dai 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 c snippets\") OR (\"tri thi dan snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using c snippets ) OR ( tri thi dan snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using c snippets") OR ("tri thi dan snippets"))) OR ("locating bugs code snippets"))*.
