Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"using java java snippets" » "using data java snippets"
"phan cau java snippets" » "phan dau java snippets", "phan cac java snippets", "phan tu java snippets", "phan cau va snippets", "phan ngu 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: "((((\"phan cau java snippets\") OR (\"using java java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( phan cau java snippets ) OR ( using java java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("phan cau java snippets") OR ("using java java snippets"))) OR ("locating bug core snippets"))*.
