Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java code snippets" » "using data code snippets"
"can cho cong snippets" » "can cao cong snippets", "can cua cong snippets", "can cac cong snippets", "chan cho cong snippets", "cap cho cong snippets", "cao cho cong 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 (\"can cho cong snippets\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( can cho cong snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("can cho cong snippets"))) OR ("locating bugs code snippets"))*.
