Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"
"dien xuong va snippets" » "dieu duong va snippets", "tien luong va snippets", "dien xuong van snippets", "dien luong va snippets", "dien duong 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: "((((\"using java java snippets\") OR (\"dien xuong va snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( dien xuong va snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("dien xuong va snippets"))) OR ("locating bug core snippets"))*.
