Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"n2 doc cua snippets" » "n2 hoc cua snippets", "n2 doi cua snippets", "n2 do cua snippets", "n1 doc cua snippets", "n3 doc cua 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: "((((\"python using java snippets\") OR (\"n2 doc cua snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( n2 doc cua snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("n2 doc cua snippets"))) OR ("locating bugs code snippets"))*.
