Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"python using java snippets" » "python using data snippets", "python using java slippers"
"su doi duc snippets" » "su do duc snippets", "su doi duy snippets", "su oi duc snippets", "sua doi duc snippets", "su dai duc snippets", "tu doi duc snippets", "su doi duc slippers"

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: "((((\"su doi duc snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( su doi duc snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("su doi duc snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
