Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"xa dung he snippets" » "xa dung code snippets", "xay dung he snippets", "xa dong he snippets", "va dung he snippets", "xa 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: (((("xa dung he snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"xa dung he snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( xa dung he snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))*.
