Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"than va du snippets" » "thanh va du snippets", "nhan va du snippets", "toan va du snippets", "than va dau snippets", "than va su snippets", "than va tu 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: "((((\"than va du snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( than va du snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("than va du snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
