Perhaps you should try some spelling variations:
"hat dan hang slices" » "hat dan ham slices", "hat ban hang slices", "hat van hang slices", "hat dat hang slices", "mat dan hang slices", "nhat danh hang 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 (\"hat dan hang slices\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java slippers ) OR ( hat dan hang slices ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippers") OR ("hat dan hang slices"))) OR ("locating bug code snippets"))*.
