Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets"
"tran sach han slippers" » "tran mach han slippers", "ngan sach han slippers", "tran manh han slippers", "tran sach tham slippers", "tran sach danh slippers", "tran sach nang slippers", "tran sach han slippery", "tran sach han grippers"
"locating bug core snippets" » "locating bug code 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 code snippets\") OR (\"tran sach han slippers\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( tran sach han slippers ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("tran sach han slippers"))) OR ("locating bug core snippets"))*.
