Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"cua dang do snippets" » "cua dang code snippets", "cua cong do snippets", "cua ban do snippets", "cua nang doc snippets", "cua dung doi snippets", "cua dang duc snippets"
"python using java snippets" » "python using data snippets"

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

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