Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"bai cua hoi snippets" » "bai cua code snippets", "ban cua hoi snippets", "dai cua hoi snippets", "bai ca hoi snippets", "bai cua moi snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data 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: "((((\"bai cua hoi snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( bai cua hoi snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("bai cua hoi snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
