Perhaps you should try some spelling variations:
"trinh quang dat snippets" » "tinh quang dat snippets", "trinh quan dat snippets", "tranh quang dat snippets", "trinh quang dai snippets", "trinh quang dam snippets", "trinh quang phat snippets", "trinh quang dat slippers"
"dung bug code snippets" » "dung dung code snippets", "dung hung code snippets", "dung rung code snippets", "dung bug code slippers", "dung bug core snippets"
"locating bug code snippets" » "locating bug code slippers", "locating bug core 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 quang dat snippets\") OR (\"dung bug code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trinh quang dat snippets ) OR ( dung bug code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trinh quang dat snippets") OR ("dung bug code snippets"))) OR ("locating bug code snippets"))*.
