Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"trinh he so snippets" » "trinh han so snippets", "trinh hoa so snippets", "trinh ky so snippets", "trinh he soi snippets", "trinh he co snippets", "trinh ho so 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 (\"trinh he so snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( trinh he so snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("trinh he so snippets"))) OR ("locating bugs code snippets"))*.
