Perhaps you should try some spelling variations:
"locating bug code slippers" » "locating bug code snippets", "locating bung code slippers", "locating bugs code slippers"
"python using java snippets" » "python using data snippets"
"dao doan va slippery" » "dao doanh va slippery", "dao dan va slippery", "dao hoan va slippery"

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: "((((\"dao doan va slippery\") OR (\"python using java snippets\"))) OR (\"locating bug code slippers\"))~".
• Removing quotes may allow a broader search: (((( dao doan va slippery ) OR ( python using java snippets ))) OR ( locating bug code slippers ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dao doan va slippery") OR ("python using java snippets"))) OR ("locating bug code slippers"))*.
