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"
"cong co dan slippery" » "dong co dan slippery", "cong cu dan slippery", "cong so dan slippery", "cong co ban slippery", "cong ca dan slippery", "cong cao dang 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: "((((\"cong co dan slippery\") OR (\"python using java snippets\"))) OR (\"locating bug code slippers\"))~".
• Removing quotes may allow a broader search: (((( cong co dan slippery ) OR ( python using java snippets ))) OR ( locating bug code slippers ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cong co dan slippery") OR ("python using java snippets"))) OR ("locating bug code slippers"))*.
