Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java slippers" » "python using data slippers", "python using java grippers"
"cong co cau slippery" » "dong co cau slippery", "cong cu cau slippery", "cong so cau slippery", "cong bo cau 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 cau slippery\") OR (\"python using java slippers\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( cong co cau slippery ) OR ( python using java slippers ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("cong co cau slippery") OR ("python using java slippers"))) OR ("locating bug core snippets"))*.
