Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"using real java snippets" » "using metal java snippets", "using raw java snippets"
"anh toan java snippets" » "anh toan va snippets", "manh toan java snippets", "anh tuan java snippets", "thanh toan java 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: "((((\"anh toan java snippets\") OR (\"using real java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( anh toan java snippets ) OR ( using real java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("anh toan java snippets") OR ("using real java snippets"))) OR ("locating bug core snippets"))*.
