Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"tran doi cua snippets" » "truan doi cua snippets", "trao doi cua snippets", "tren doi cua snippets", "tran hoi cua snippets", "tran dai cua snippets", "tran dong cua 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 doi cua snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( tran doi cua snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("tran doi cua snippets"))) OR ("locating bugs code snippets"))*.
