Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"quan ca dua snippets" » "quan cua dua snippets", "quan cau dua snippets", "quan ha dua snippets", "quan cay dua snippets", "quan ca cua snippets", "quan ca da 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 ca 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 ca dua snippets\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( quan ca dua snippets ) OR ( python using java snippets ))) OR ( locating bug core snippets ))*.
