Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java core snippets" » "using data core snippets"
"dung von chi snippets" » "dong von chi snippets", "dung cong chi snippets", "dung va chi snippets", "dung van chi snippets", "dung con chi snippets", "dung vuong chi 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 core snippets\") OR (\"dung von chi snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java core snippets ) OR ( dung von chi snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java core snippets") OR ("dung von chi snippets"))) OR ("locating bugs code snippets"))*.
