Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"hoc phan cuc snippets" » "hoc dan cuc snippets", "hoc pho cuc snippets", "hoc phan duc snippets", "hoc phan cac snippets", "hoc pham cuc 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 (\"hoc phan cuc snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( hoc phan cuc snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("hoc phan cuc snippets"))) OR ("locating bugs code snippets"))*.
