Perhaps you should try some spelling variations:
"hai trong code snippets" » "hai trong cong snippets", "hai trong co snippets", "hai trong che snippets", "tai trong code snippets", "bai trong code snippets", "dai trong code snippets", "hai trong code slippers"
"using low java snippets" » "using low java slippers"
"locating bug code snippets" » "locating bug code slippers", "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 low java snippets\") OR (\"hai trong code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using low java snippets ) OR ( hai trong code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using low java snippets") OR ("hai trong code snippets"))) OR ("locating bug code snippets"))*.
