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