Perhaps you should try some spelling variations:
"data using java snippets" » "data using data snippets"
"dung thi code snippets" » "dung tai code snippets", "dung tri code snippets", "dung chi code snippets", "dung thi cong snippets", "dung thi hoe 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: "((((\"dung thi code snippets\") OR (\"data using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( dung thi code snippets ) OR ( data using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung thi code snippets") OR ("data using java snippets"))) OR ("locating bug core snippets"))*.
