Perhaps you should try some spelling variations:
"hanh java java snippets" » "hanh va java snippets"
"dung nam cham snippets" » "dong nam cham snippets", "dung lam cham snippets", "sung nam cham snippets", "dung nang cham snippets", "dung nam chi snippets", "dung nam cao snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core 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: "((((\"hanh java java snippets\") OR (\"dung nam cham snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( hanh java java snippets ) OR ( dung nam cham snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("hanh java java snippets") OR ("dung nam cham snippets"))) OR ("locating bug code snippets"))*.
