Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"using data java snippets" » "using java java snippets", "using sat java snippets", "missing data java snippets"
"ba tran van snippets" » "ba luan van snippets", "ban tran van snippets", "bao tran van snippets", "ba trao van 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 java snippets\") OR (\"ba tran van snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using data java snippets ) OR ( ba tran van snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using data java snippets") OR ("ba tran van snippets"))) OR ("locating bug core snippets"))*.
