Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"so cac code snippets" » "so cac cong snippets", "so cac co snippets", "so cac che snippets", "sao cac code snippets", "so cap code snippets", "o cac 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: (((("so cac code snippets") OR ("python using java snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"so cac code snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( so cac code snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))*.
