Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"so dung cho snippets" » "so dung code snippets", "su dung cho snippets", "hoc dung cho snippets", "noi dung cho 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.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("so dung cho snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"so dung cho snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( so dung cho snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))*.
