Perhaps you should try some spelling variations:
"trong canh code snippets" » "trong anh code snippets", "trong cach code snippets", "trong can code snippets", "trong canh code slippers"
"gian dan code snippets" » "gian lang code snippets", "gian dan de snippets", "gian dan 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: "((((\"gian dan code snippets\") OR (\"trong canh code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( gian dan code snippets ) OR ( trong canh code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("gian dan code snippets") OR ("trong canh code snippets"))) OR ("locating bug code snippets"))*.
