Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"cac van hang snippets" » "cac van khang snippets", "cac van hoang snippets", "cac van thang snippets", "cac dan hang snippets", "cac van hang slippers"
"python using a snippets" » "python using a 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: "((((\"python using a snippets\") OR (\"cac van hang snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using a snippets ) OR ( cac van hang snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using a snippets") OR ("cac van hang snippets"))) OR ("locating bugs code snippets"))*.
