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