Perhaps you should try some spelling variations:
"python using java slippery" » "python using data slippery"
"le cau code snippets" » "le cau cong snippets", "le cau de snippets", "le cfd code snippets", "ke cau code snippets", "le mau code snippets", "le cap code snippets"
"locating bug code slippers" » "locating bung code slippers", "locating bugs 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 (\"le cau code snippets\"))) OR (\"locating bug code slippers\"))~".
• Removing quotes may allow a broader search: (((( python using java slippery ) OR ( le cau code snippets ))) OR ( locating bug code slippers ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippery") OR ("le cau code snippets"))) OR ("locating bug code slippers"))*.
