Perhaps you should try some spelling variations:
"vi using code snippets" » "vi using cfd snippets", "vi using one snippets", "vi sinh code snippets", "_ using code snippets", "vi ung code snippets", "vi using code slippers"
"using data java snippets" » "using java java snippets", "using sat java snippets", "missing data java snippets", "using data java slippers"
"locating bug code snippets" » "locating bug code slippers", "locating bung code snippets", "locating bugs code snippets"

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