Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets"
"tue nhan vao snippets" » "cu nhan vao snippets", "tue nhan tao snippets", "tue nhan va snippets", "tue nhan vat snippets"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("python using raw snippets") OR ("tue nhan vao snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using raw snippets\") OR (\"tue nhan vao snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( python using raw snippets ) OR ( tue nhan vao snippets ))) OR ( locating bug core snippets ))*.
