Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using java code snippets" » "using data code snippets", "using java code slippers"
"dan tran van snippets" » "dang tran van snippets", "tan tran van snippets", "dan than van snippets", "dan luan van snippets", "dan tran van slippers"

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 (\"dan tran van snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dan tran van snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dan tran van snippets"))) OR ("locating bugs code snippets"))*.
