Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets", "python using java slippers"
"cu so trong snippets" » "cu so truong snippets", "cu ro trong snippets", "cu co trong snippets", "cu soc trong snippets", "cua so trong snippets", "co so trong snippets", "cu so trong 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 (\"cu so trong snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( cu so trong snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("cu so trong snippets"))) OR ("locating bug code snippets"))*.
