ORA-18170: FTST0011FTWindow and FTDistance restriction Cause: An implementation may restrict the use of FTWindow andFTDistance to
an FTOr that is either a single FTWords or a combination of FTWords involving

an expression is found that violates this restriction and the implementation
enforces this restriction. Action: FollowFTWindow and FTDistance restriction.
