Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets", "locating bugs code slippers"
"using java code snippets" » "using data code snippets", "using java code slippers"
"van qua dat snippets" » "van quan dat snippets", "van quy dat snippets", "van cua dat snippets", "van qua da snippets", "van qua dan snippets", "van qua dat slippers"

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 (\"van qua dat snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( van qua dat snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("van qua dat snippets"))) OR ("locating bugs code snippets"))*.
