Perhaps you should try some spelling variations:
"using java java snippets" » "using data java snippets", "using java java slippers"
"cac dat trong snippets" » "cac dot trong snippets", "cac vat trong snippets", "cac cay trong snippets", "cac dan trong snippets", "cai dat trong snippets", "cac dai trong snippets", "cac dat trong slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets", "locating bug core 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: "((((\"cac dat trong snippets\") OR (\"using java java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( cac dat trong snippets ) OR ( using java java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cac dat trong snippets") OR ("using java java snippets"))) OR ("locating bug code snippets"))*.
