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", "trinh vat code slippers"
"dung sai code snippets" » "dung tai code snippets", "dung va code snippets", "dung dat code snippets", "dung sai 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: "((((\"trinh vat code snippets\") OR (\"dung sai code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trinh vat code snippets ) OR ( dung sai code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trinh vat code snippets") OR ("dung sai code snippets"))) OR ("locating bug code snippets"))*.
