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"
"dong toc hoc snippets" » "dong hoc hoc snippets", "dong tac hoc snippets", "dong tot hoc snippets", "dong toan hoc snippets", "dong duoc hoc 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 (\"dong toc hoc snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using data code snippets ) OR ( dong toc hoc snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using data code snippets") OR ("dong toc hoc snippets"))) OR ("locating bug code snippets"))*.
