Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"ly nen trong snippets" » "ly ben trong snippets", "ly yen trong snippets", "ly nhien trong snippets"
"python using raw snippets" » "python using real snippets", "python using a snippets", "python using low snippets"

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