Perhaps you should try some spelling variations:
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"danh cau bo snippets" » "danh dau bo snippets", "danh ca bo snippets", "danh hau bo snippets", "danh cau bao snippets", "danh cau do snippets", "danh can bo snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core 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: "((((\"danh cau bo snippets\") OR (\"python using data snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( danh cau bo snippets ) OR ( python using data snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("danh cau bo snippets") OR ("python using data snippets"))) OR ("locating bug code snippets"))*.
