ORA-18170: FTST0011 FTWindow and FTDistance restriction

ORA-18170: FTST0011 FTWindow and FTDistance restriction


Cause:


An implementation may restrict the use of FTWindow and FTDistance to an FTOr that is either a single FTWords or a combination of FTWords involving only the operators && and ||. If it a static error if, during the static analysis phase, an expression is found that violates this restriction and the implementation enforces this restriction.



Action:


Follow FTWindow and FTDistance restriction.
