Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"de mat code snippets" » "de rate code snippets", "de mat co snippets", "de dat code snippets", "de bat code snippets", "de gat 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 ("de mat 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 (\"de mat code snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( de mat code snippets ))) OR ( locating bug core snippets ))*.
