Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"trong cac code snippets" » "trong cac cong snippets", "trong cac co snippets", "trong cac che snippets"
"trinh c model snippets" » "trinh co model snippets", "trinh _ model snippets", "trinh cau model snippets", "trinh a model snippets", "trinh 1 model 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: "((((\"trinh c model snippets\") OR (\"trong cac code snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( trinh c model snippets ) OR ( trong cac code snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trinh c model snippets") OR ("trong cac code snippets"))) OR ("locating bugs code snippets"))*.
