Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"quang tran c snippets" » "quang tuan c snippets", "quang trung c snippets", "quang thanh c snippets", "quang tran _ snippets", "quang tran v snippets", "quang tran duc 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 (\"quang tran c snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( quang tran c snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("quang tran c snippets"))) OR ("locating bugs code snippets"))*.
