Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"cu dan chi snippets" » "cu danh chi snippets", "cu dan thi snippets", "cu van chi snippets", "cua dan chi snippets", "ca dan chi snippets", "co dan chi 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: "((((\"cu dan chi snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( cu dan chi snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cu dan chi snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
