Perhaps you should try some spelling variations:
"using java java snippets" » "using data java snippets"
"bo tuong ho snippets" » "bo truong ho snippets", "bao tuong ho snippets", "bo thong ho snippets", "bo tong hop snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core 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 (\"bo tuong ho snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( bo tuong ho snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("bo tuong ho snippets"))) OR ("locating bug code snippets"))*.
