Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"hoi qua code snippets" » "hoi qua cong snippets", "hoi qua co snippets", "hoi qua con snippets", "hoi cua code snippets", "hoa qua code snippets", "hai quan 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: (((("python using java snippets") OR ("hoi qua code snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using java snippets\") OR (\"hoi qua code snippets\"))) OR (\"locating bug core snippets\"))".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( hoi qua code snippets ))) OR ( locating bug core snippets )).
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("hoi qua code snippets"))) OR ("locating bug core snippets"))*.
