Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"quan so dua snippets" » "quan su dua snippets", "quan doi dua snippets", "quan sat dua snippets", "quan so du snippets", "quan so dia snippets", "quan ho dua snippets"

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

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