Perhaps you should try some spelling variations:
"trong cach code snippets" » "trong mach code snippets", "trong canh code snippets", "trong hach code snippets", "trong cach de snippets", "trong cach con snippets"
"trong cac cau snippets" » "trong cac mau snippets", "trong bac cau snippets", "trong ca cau 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: "((((\"trong cach code snippets\") OR (\"trong cac cau snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( trong cach code snippets ) OR ( trong cac cau snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("trong cach code snippets") OR ("trong cac cau snippets"))) OR ("locating bug code snippets"))*.
