Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"cong can cau snippets" » "cong san cau snippets", "cong tan cau snippets", "cong dan cau snippets", "cong van cau snippets", "cong ban cau snippets", "cong ca cau 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 (\"cong can cau snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( cong can cau snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("cong can cau snippets"))) OR ("locating bugs code snippets"))*.
