Perhaps you should try some spelling variations:
"python using java snippets" » "python using data snippets"
"lieu da cau snippets" » "lieu dao cau snippets", "lieu dai cau snippets", "lieu dia cau snippets", "lieu dat cau snippets", "lieu va cau snippets"
"locating bug code snippets" » "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 (\"lieu da cau snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( lieu da cau snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("lieu da cau snippets"))) OR ("locating bug code snippets"))*.
