Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"dai dung cho snippets" » "dai dung code snippets", "dai duong cho snippets", "dan dung cho snippets", "mai dung cho snippets"
"using data java snippets" » "using java java snippets", "using sat java snippets", "missing data java 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 data java snippets\") OR (\"dai dung cho snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using data java snippets ) OR ( dai dung cho snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using data java snippets") OR ("dai dung cho snippets"))) OR ("locating bug core snippets"))*.
