Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets", "using java core snippets", "using java code slippers"
"sam danh thin snippets" » "sam canh thin snippets", "sam danh thanh snippets", "sam danh thang snippets", "sam doanh thin snippets", "nam danh thin snippets", "sau danh thin snippets", "sam danh thin slippers"
"locating bug code snippets" » "locating bug core snippets", "locating bug code slippers", "locating bung code snippets", "locating bugs 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 (\"sam danh thin snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( sam danh thin snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("sam danh thin snippets"))) OR ("locating bug code snippets"))*.
