Perhaps you should try some spelling variations:
"using java java snippets" » "using data java snippets"
"di dong code snippets" » "di dong co snippets", "di dong che snippets", "di dong cong snippets", "dien dong code snippets", "dao dong code snippets", "hoi dong code snippets"
"locating bug core snippets" » "locating bug code snippets"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("using java java snippets") OR ("di dong code snippets"))) OR ("locating bug core snippets"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"using java java snippets\") OR (\"di dong code snippets\"))) OR (\"locating bug core snippets\"))*".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( di dong code snippets ))) OR ( locating bug core snippets ))*.
