Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"den va lua snippets" » "dien va lua snippets", "den vai lua snippets", "den vay lua snippets", "den va luat snippets", "den ca lua snippets", "den vi lua snippets", "den va lua 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: "((((\"python using java snippets\") OR (\"den va lua snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( den va lua snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("den va lua snippets"))) OR ("locating bug code snippets"))*.
