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