Perhaps you should try some spelling variations:
"locating bugs code snippets" » "locating bug code snippets"
"using java java slippers" » "using data java slippers", "using java java slippery", "using java 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"

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