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 slippery" » "python using data slippery"
"van de nhan snippets" » "van do nhan snippets", "van tue nhan snippets", "van de thanh 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: "((((\"van de nhan snippets\") OR (\"python using java slippery\"))) OR (\"locating bug code slippers\"))~".
• Removing quotes may allow a broader search: (((( van de nhan snippets ) OR ( python using java slippery ))) OR ( locating bug code slippers ))~.
• Adding a wildcard symbol may retrieve word variants: (((("van de nhan snippets") OR ("python using java slippery"))) OR ("locating bug code slippers"))*.
