Perhaps you should try some spelling variations:
"locating bbug code snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"
"van dung cua snippets" » "van dong cua snippets", "xay dung cua snippets", "tin dung cua snippets", "van dung luan snippets", "van dung cho 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: "((((\"van dung cua snippets\") OR (\"using java java snippets\"))) OR (\"locating bbug code snippets\"))~".
• Removing quotes may allow a broader search: (((( van dung cua snippets ) OR ( using java java snippets ))) OR ( locating bbug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("van dung cua snippets") OR ("using java java snippets"))) OR ("locating bbug code snippets"))*.
