Perhaps you should try some spelling variations:
"tri noi code snippets" » "tri noi cong snippets", "tri noi co snippets", "tri noi de snippets", "tri doi code snippets", "tri moi code snippets", "tri ngoai code snippets", "tri noi code slippers"
"python using a snippets" » "python using a slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code 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 a snippets\") OR (\"tri noi code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using a snippets ) OR ( tri noi code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using a snippets") OR ("tri noi code snippets"))) OR ("locating bug code snippets"))*.
