Perhaps you should try some spelling variations:
"python using java slippery" » "python using data slippery", "python using java slippers"
"thuc dai so snippets" » "thuc dan so snippets", "thuc day so snippets", "thuc tai so snippets"
"locating bug code snippets" » "locating bung code snippets", "locating bugs code snippets", "locating bug core 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: "((((\"thuc dai so snippets\") OR (\"python using java slippery\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( thuc dai so snippets ) OR ( python using java slippery ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("thuc dai so snippets") OR ("python using java slippery"))) OR ("locating bug code snippets"))*.
