Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"python using java snippets" » "python using data snippets", "python using java slippers"
"du a code snippets" » "du va code snippets", "du ha code snippets", "du _ code snippets", "du a code slippers"

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: "((((\"du a code snippets\") OR (\"python using java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( du a code snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("du a code snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
