Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets"
"dung cac tu snippets" » "luong cac tu snippets", "dung cho tu snippets", "dung tai tu snippets", "dung cac thu snippets", "dung cach tu snippets", "dung cac du snippets"
"locating bug core snippets" » "locating bug code 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 cac tu snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( dung cac tu snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("dung cac tu snippets"))) OR ("locating bug core snippets"))*.
