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"
"phan le dat snippets" » "pham le dat snippets", "phan mem dat snippets", "phan lap dat snippets", "phan le dan snippets", "phan de dat snippets", "phan le dac snippets"

You may be able to get more results by adjusting your search query.

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