Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"thi tran ngoc snippets" » "thi tran quoc snippets", "thi trang ngoc snippets", "thi thanh ngoc snippets", "thi lan ngoc snippets"
"python using a slippers" » "python using a slippery", "python using a grippers"

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: "((((\"thi tran ngoc snippets\") OR (\"python using a slippers\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( thi tran ngoc snippets ) OR ( python using a slippers ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thi tran ngoc snippets") OR ("python using a slippers"))) OR ("locating bugs code snippets"))*.
