Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"doi danh o snippets" » "doi doanh o snippets", "do danh o snippets", "doi hanh o snippets", "doi danh co snippets", "doi dinh o snippets", "doi danh cho snippets"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"doi danh o snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( doi danh o snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("doi danh o snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
