Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using sat snippets" » "python using data snippets", "python using a snippets", "python using raw snippets"
"den dung dat snippets" » "dan dung dat snippets", "den vung dat snippets", "den dong dat snippets", "den dung va snippets", "den dung tai 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: "((((\"den dung dat snippets\") OR (\"python using sat snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( den dung dat snippets ) OR ( python using sat snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("den dung dat snippets") OR ("python using sat snippets"))) OR ("locating bug core snippets"))*.
