Perhaps you should try some spelling variations:
"nhap van tham slices" » "nhap van ham slices", "nha van tham slices", "nhan van tham slices", "phap van tham slices", "nhap van thanh slices", "nhap van tuan slices", "nhap van chat 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 (\"nhap van tham slices\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java slippers ) OR ( nhap van tham slices ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippers") OR ("nhap van tham slices"))) OR ("locating bug code snippets"))*.
