Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"viet a ca snippets" » "viet ha ca snippets", "viet ca ca snippets", "viet o ca snippets", "viet va ca snippets", "viet am ca snippets", "viet na ca 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 (\"viet a ca snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( viet a ca snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("viet a ca snippets"))) OR ("locating bugs code snippets"))*.
