Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"pha du can snippets" » "pham duc can snippets", "pham duy can snippets", "phan duc can snippets", "pha duy can snippets", "pha su can snippets", "pha tu can 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: "((((\"pha du can snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( pha du can snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("pha du can snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
