• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"del science all over\") OR (\"_ sciences book over\"))) OR (\"best science food over\"))~".
• Removing quotes may allow a broader search: (((( del science all over ) OR ( _ sciences book over ))) OR ( best science food over ))~.
• Adding a wildcard symbol may retrieve word variants: (((("del science all over") OR ("_ sciences book over"))) OR ("best science food over"))*.
