Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"su phan o2 snippets" » "su pham o2 snippets", "su phat o2 snippets", "so phan o2 snippets", "su phan o snippets", "su phan hoa snippets", "su phan bon 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: "((((\"su phan o2 snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( su phan o2 snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("su phan o2 snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
