Perhaps you should try some spelling variations:
"python using java slippery" » "python using data slippery", "python using java slippers"
"pham can ham slices" » "pham van ham slices", "pham lan ham slices", "pham ca ham slices", "pham ban ham slices", "pham cac ham slices", "pham can hai slices"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core snippets", "locating bug code slippers"

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 slippery\") OR (\"pham can ham slices\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java slippery ) OR ( pham can ham slices ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippery") OR ("pham can ham slices"))) OR ("locating bug code snippets"))*.
