Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"dao noi dat snippets" » "dau noi dat snippets", "dao voi dat snippets", "nao noi dat snippets", "dao hoi dat snippets", "dao noi bat snippets", "dao noi da 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: "((((\"dao noi dat snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dao noi dat snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dao noi dat snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
