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