Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"xa dung lan snippets" » "xa dung luan snippets", "xa dung land snippets", "xa dung lam snippets", "xay dung lan snippets", "xa dong lan snippets", "va dung lan 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 lan 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 lan snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( xa dung lan snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets ))*.
