Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java can snippets" » "using data can snippets"
"dung vat code snippets" » "dung va code snippets", "dong vat code snippets", "dung dat code snippets", "dung rate code snippets", "dung vat co snippets", "dung vat de 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 can snippets\") OR (\"dung vat code snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java can snippets ) OR ( dung vat code snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java can snippets") OR ("dung vat code snippets"))) OR ("locating bugs code snippets"))*.
