Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"data using java snippets" » "data using data snippets"
"dung cac che snippets" » "luong cac che snippets", "dung cho che snippets", "dung tai che snippets", "dung cac he snippets", "dung cac chien snippets", "dung cac chat 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: "((((\"data using java snippets\") OR (\"dung cac che snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( data using java snippets ) OR ( dung cac che snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("data using java snippets") OR ("dung cac che snippets"))) OR ("locating bugs code snippets"))*.
