Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java snippets" » "python using data snippets"
"than duc f slippery" » "tran duc f slippery", "phan duc f slippery", "than doc f slippery", "than duc _ slippery", "than duc m slippery", "than duc y slippery", "than duc f slippers"

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: "((((\"than duc f slippery\") OR (\"python using java snippets\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( than duc f slippery ) OR ( python using java snippets ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("than duc f slippery") OR ("python using java snippets"))) OR ("locating bug core snippets"))*.
