Perhaps you should try some spelling variations:
"trinh cai code snippets" » "trinh tai code snippets", "trinh cau code snippets", "trinh cac code snippets", "trinh cfd code snippets", "trinh cai code slippers"
"trong cac code snippets" » "trong cac cong snippets", "trong cac co snippets", "trong cac che snippets", "trong cac code 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: "((((\"trong cac code snippets\") OR (\"trinh cai code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trong cac code snippets ) OR ( trinh cai code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trong cac code snippets") OR ("trinh cai code snippets"))) OR ("locating bug code snippets"))*.
