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