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"
"lieu lam vu slippery" » "lieu lai vu slippery", "lieu tham vu slippery", "lieu va vu slippery", "lieu sam vu 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: "((((\"python using java slippers\") OR (\"lieu lam vu slippery\"))) OR (\"locating bug core snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java slippers ) OR ( lieu lam vu slippery ))) OR ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippers") OR ("lieu lam vu slippery"))) OR ("locating bug core snippets"))*.
