Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"van cua con snippets" » "vang cua con snippets", "ban cua con snippets", "dan cua con snippets", "van cua cong snippets", "van cua co snippets", "van cua can 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 (\"van cua con snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( van cua con snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("van cua con snippets"))) OR ("locating bugs code snippets"))*.
