Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using real snippets" » "python using metal snippets", "python using raw snippets"
"ly ve trong snippets" » "ly le trong snippets", "ly ke trong snippets", "ly ve tuong snippets", "ly va trong snippets"

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

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