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