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