Perhaps you should try some spelling variations:
"using java java snippets" » "using data java snippets"
"va nang code snippets" » "va nang co snippets", "va nang cong snippets", "van nang code snippets", "da nang code snippets", "cam nang code snippets"
"locating bug code slippers" » "locating bung code slippers", "locating bugs code slippers"

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: "((((\"va nang code snippets\") OR (\"using java java snippets\"))) OR (\"locating bug code slippers\"))~".
• Removing quotes may allow a broader search: (((( va nang code snippets ) OR ( using java java snippets ))) OR ( locating bug code slippers ))~.
• Adding a wildcard symbol may retrieve word variants: (((("va nang code snippets") OR ("using java java snippets"))) OR ("locating bug code slippers"))*.
