Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"cong co cham snippets" » "dong co cham snippets", "cong cu cham snippets", "cong so cham snippets", "cong ca cham snippets", "cong co champa snippets", "cong cao chat 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 co cham snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( cong co cham snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("cong co cham snippets"))) OR ("locating bugs code snippets"))*.
