Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"hoang cd cac snippets" » "hoang cao cac snippets", "hoang chi cac snippets", "hoang _ cac snippets", "hoang ca cac snippets", "hoang co cac 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 (\"hoang cd cac snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( hoang cd cac snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("hoang cd cac snippets"))) OR ("locating bugs code snippets"))*.
