Perhaps you should try some spelling variations:
"using data java snippets" » "using java java snippets", "using sat java snippets", "missing data java snippets"
"van hung code snippets" » "van dung code snippets", "manh hung code snippets", "van duong 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 (\"van hung code snippets\"))) OR (\"locating bug code slippers\"))~".
• Removing quotes may allow a broader search: (((( using data java snippets ) OR ( van hung code snippets ))) OR ( locating bug code slippers ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using data java snippets") OR ("van hung code snippets"))) OR ("locating bug code slippers"))*.
