Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"dang tran so snippets" » "dang thanh so snippets", "quang tran so snippets", "hoang tran so snippets", "dang tran si snippets", "dang tran sy snippets", "dang than so 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: "((((\"using java code snippets\") OR (\"dang tran so snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dang tran so snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dang tran so snippets"))) OR ("locating bugs code snippets"))*.
