Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"do thu nhap snippets" » "do thu ha snippets", "do khu nha snippets", "do thuc nhap snippets", "doi thu nhap snippets", "do thuy nhap snippets"

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

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