Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using java java snippets" » "using data java snippets", "using java java slippers"
"nhan dam van snippets" » "nhan dan van snippets", "nhan tam van snippets", "nhan nam van snippets", "nhan dao van snippets", "nhan pham van snippets", "nhan dam 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: "((((\"nhan dam van snippets\") OR (\"using java java snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( nhan dam van snippets ) OR ( using java java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("nhan dam van snippets") OR ("using java java snippets"))) OR ("locating bugs code snippets"))*.
