Perhaps you should try some spelling variations:
"can tranh code snippets" » "can tranh co snippets", "canh tranh code snippets", "tan tran code snippets", "van ranh code snippets", "can tranh code slippers"
"dung vat code snippets" » "dung va code snippets", "dong vat code snippets", "dung dat code snippets", "dung rate code snippets", "dung vat co snippets", "dung vat de snippets", "dung vat 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: "((((\"can tranh code snippets\") OR (\"dung vat code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( can tranh code snippets ) OR ( dung vat code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("can tranh code snippets") OR ("dung vat code snippets"))) OR ("locating bug code snippets"))*.
