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