Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"trinh san co snippets" » "trinh han co snippets", "trinh van co snippets", "trinh quan co snippets", "trinh ban co snippets", "trinh sang cho 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 san co snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( trinh san co snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("trinh san co snippets"))) OR ("locating bugs code snippets"))*.
