Perhaps you should try some spelling variations:
"python using data snippets" » "python using java snippets", "python using sat snippets", "python missing data snippets"
"hoi anh code snippets" » "hoi anh co snippets", "hoi anh cong snippets", "hoi danh code snippets", "hoc anh code snippets", "hai anh code snippets"
"locating bug core snippets" » "locating bug code snippets"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("hoi anh code snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"hoi anh code snippets\") OR (\"python using data snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( hoi anh code snippets ) OR ( python using data snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("hoi anh code snippets") OR ("python using data snippets"))) OR ("locating bug core snippets"))*.
