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