Perhaps you should try some spelling variations:
"locating bug core snippets" » "locating bug code snippets"
"python using java slippery" » "python using data slippery"
"cong co cau slippers" » "dong co cau slippers", "cong cu cau slippers", "cong so cau slippers", "cong bo cau slippers", "cong co cau grippers"

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