Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"lo van trong snippets" » "lo van truong snippets", "lo vang trong snippets", "lo ban trong snippets", "le van trong snippets", "vo van trong snippets", "so van trong snippets"
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low 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: "((((\"lo van trong snippets\") OR (\"python using raw snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( lo van trong snippets ) OR ( python using raw snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("lo van trong snippets") OR ("python using raw snippets"))) OR ("locating bug core snippets"))*.
