Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"dung tan cua snippets" » "dung toan cua snippets", "duong tan cua snippets", "dung tai cua snippets", "dung than cua snippets", "dung tang cua 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 (\"dung tan cua snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dung tan cua snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dung tan cua snippets"))) OR ("locating bugs code snippets"))*.
