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 mo snippets" » "hoi dan mo snippets", "doi ban mo snippets", "doi dau mo snippets", "doi dan mon snippets", "doi dan so snippets", "doi fan mo 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 mo snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( doi dan mo snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("doi dan mo snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
