Perhaps you should try some spelling variations:
"using data java slippers" » "using java java slippers", "using sat java slippers", "missing data java slippers", "using data java slippery", "using data java grippers"
"vi using raw snippets" » "vi using real snippets", "vi using a snippets", "vi using low snippets", "vi sinh raw snippets", "_ using raw snippets", "vi ung raw snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core 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 raw snippets\") OR (\"using data java slippers\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( vi using raw snippets ) OR ( using data java slippers ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("vi using raw snippets") OR ("using data java slippers"))) OR ("locating bug code snippets"))*.
