Perhaps you should try some spelling variations:
"using java code snippets" » "using data code snippets", "using java core snippets", "using java code slippers"
"nhung hat dat snippets" » "nhung phat dat snippets", "nhung pham dat snippets", "nhung kham dat snippets", "nhung hat dan snippets", "nhung tat dat snippets", "nhung hat dam snippets", "nhung hat dat 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 (\"nhung hat dat snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( nhung hat dat snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("nhung hat dat snippets"))) OR ("locating bug code snippets"))*.
