Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"cu cuc code snippets" » "cu bug code snippets", "cu cfd code snippets", "cua cuc code snippets", "cu cu code snippets", "cu cua 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: (((("cu cuc 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: "((((\"cu cuc code snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( cu cuc code snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))*.
