• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"python using java slippers\") OR (\"lap luan pham slices\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( python using java slippers ) OR ( lap luan pham slices ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("python using java slippers") OR ("lap luan pham slices"))) OR ("locating bug code snippets"))*.
