Perhaps you should try some spelling variations:
"using java java snippets" » "using data java snippets"
"dai cong code snippets" » "dai cong cong snippets", "dai cong co snippets", "dai cong che snippets", "dai cuong code snippets", "tai cong code snippets", "doi cong 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: "((((\"using java java snippets\") OR (\"dai cong code snippets\"))) OR (\"locating bug code slippers\"))~".
• Removing quotes may allow a broader search: (((( using java java snippets ) OR ( dai cong code snippets ))) OR ( locating bug code slippers ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java java snippets") OR ("dai cong code snippets"))) OR ("locating bug code slippers"))*.
