Perhaps you should try some spelling variations:
"python using sat snippets" » "python using data snippets", "python using a snippets", "python using raw snippets"
"van dong dat slippers" » "van dong vat slippers", "van dung dat slippers", "van dong ha slippers", "van dong dat slippery", "van dong dat grippers"
"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: "((((\"van dong dat slippers\") OR (\"python using sat snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( van dong dat slippers ) OR ( python using sat snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("van dong dat slippers") OR ("python using sat snippets"))) OR ("locating bug code snippets"))*.
