Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"tran ve do snippets" » "tran vu do snippets", "toan ve do snippets", "tran v do snippets", "tran ve dao snippets", "tran ve doi snippets", "tran va do 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 (\"tran ve do snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java snippets ) OR ( tran ve do snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java snippets") OR ("tran ve do snippets"))) OR ("locating bugs code snippets"))*.
