Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"den cac su snippets" » "dien cac su snippets", "dan cac su snippets", "de cac su snippets", "den cach su snippets", "den cac sau snippets", "den cac du snippets", "den cac su slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core snippets"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"den cac su snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( den cac su snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("den cac su snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
