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.

ORA-18170：FTST0011 FTWindow和FTDistance限制,
.原因：实现可能会限制对FTOr使用FTWindow和FTDistance，该FTOr是单个FTWords或仅包含运算符&&和||的FTORD的组合。如果它是静态错误，如果在静态分析阶段期间，发现违反此限制的表达式，并且实现强制实施此限制。,
.操作：遵循FTWindow和FTDistance限制。,
