Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"duc a line snippets" » "duc a link snippets", "duc a linear snippets", "duc bam line snippets", "duc va line snippets", "duc ha line snippets", "duc _ line 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: "((((\"duc a line snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( duc a line snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("duc a line snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
