Perhaps you should try some spelling variations:
"using java java snippets" » "using data java snippets", "using java java slippers"
"nhan thi van snippets" » "nhanh thi van snippets", "nhan tai van snippets", "phan thi van snippets", "nhan thi lan snippets", "nhan thi hanh snippets", "nhan thi nang snippets", "nhan thi van slippers"
"locating bug code snippets" » "locating bug code slippers", "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: "((((\"nhan thi van snippets\") OR (\"using java java snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( nhan thi van snippets ) OR ( using java java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("nhan thi van snippets") OR ("using java java snippets"))) OR ("locating bug code snippets"))*.
