Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"doi dan o snippets" » "hoi dan o snippets", "doi ban o snippets", "doi dau o snippets", "doi dan mo snippets", "doi dan so snippets", "doi doan o 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 dan o snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( doi dan o snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("doi dan o snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
