Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java core snippets" » "using data core snippets"
"dung chet co snippets" » "dung chat co snippets", "dung che co snippets", "dung chien co snippets", "dung cheo co snippets", "dung chet o 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 chet co snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java core snippets ) OR ( dung chet co snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java core snippets") OR ("dung chet co snippets"))) OR ("locating bugs code snippets"))*.
