Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"duc dan tp snippets" » "duoc dan tp snippets", "duc tan tp snippets", "duc dai tp snippets", "duc dan tu snippets", "duc dan ap snippets", "duc da tp snippets", "duc dan tp 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: "((((\"duc dan tp snippets\") OR (\"python using java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( duc dan tp snippets ) OR ( python using java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("duc dan tp snippets") OR ("python using java snippets"))) OR ("locating bug code snippets"))*.
