Perhaps you should try some spelling variations:
"pham va chat slices" » "pham va ham slices", "pham van chat slices", "pham ma chat slices", "pham tai chat slices", "pham va phat slices", "pham cao 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 (\"pham va chat slices\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java slippers ) OR ( pham va chat slices ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippers") OR ("pham va chat slices"))) OR ("locating bug code snippets"))*.
