• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("christianity and other religions -- islam.") OR ("christianity and other religious -- islam."))) OR ("christianity and other religion -- islam."))) OR ("christianity and other reflections -- islam."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"christianity and other religions -- islam.\") OR (\"christianity and other religious -- islam.\"))) or (\"christianity and other religion -- islam.\"))) or (\"christianity and other reflections -- islam.\"))~".
• Removing quotes may allow a broader search: (((((( christianity and other religions -- islam. ) OR ( christianity and other religious -- islam. ))) or ( christianity and other religion -- islam. ))) or ( christianity and other reflections -- islam. ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("christianity and other religions -- islam.") OR ("christianity and other religious -- islam."))) or ("christianity and other religion -- islam."))) or ("christianity and other reflections -- islam."))*.
