Perhaps you should try some spelling variations:
"hoi dan nhan slices" » "hoi dan ham slices", "hoi danh nhan slices", "hoi dan chan slices", "hoi van nhan slices", "hoa dan nhan slices", "hoc dan nhan slices", "hoi dap nhan slices"
"python using java slippers" » "python using data slippers", "python using java slippery", "python using java grippers"
"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: "((((\"python using java slippers\") OR (\"hoi dan nhan slices\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java slippers ) OR ( hoi dan nhan slices ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippers") OR ("hoi dan nhan slices"))) OR ("locating bug code snippets"))*.
