Perhaps you should try some spelling variations:
"trinh vat code snippets" » "trinh van code snippets", "trinh luat code snippets", "sinh vat code snippets", "trinh rate code snippets", "trinh vat co snippets", "trinh vat de snippets"
"dung dat de snippets" » "dung va de snippets", "dung tai de snippets", "dung vat de snippets", "dung hat de snippets", "dung dat dien snippets"
"locating bug code snippets" » "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: "((((\"trinh vat code snippets\") OR (\"dung dat de snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trinh vat code snippets ) OR ( dung dat de snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trinh vat code snippets") OR ("dung dat de snippets"))) OR ("locating bug code snippets"))*.
