Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"tran toan do snippets" » "tranh toan do snippets", "tran tuan do snippets", "tran tan do snippets", "tran toan ho snippets", "tran toan co snippets", "tran toan du 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 (\"tran toan do snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( tran toan do snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("tran toan do snippets"))) OR ("locating bugs code snippets"))*.
