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"
"phap ngu java snippets" » "nhat ngu java snippets", "han ngu java snippets", "phap tu java snippets", "phap ngu va 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: "((((\"phap ngu java snippets\") OR (\"using data java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( phap ngu java snippets ) OR ( using data java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("phap ngu java snippets") OR ("using data java snippets"))) OR ("locating bug core snippets"))*.
