文档解释
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.
官方解释
常见案例
一般处理方法及步骤
1.首先，检测客户端是否正确地访问FTService。检查它是否正确地设置了FTWindow和FTDistance参数。
2.如果客户端正确地设置了FTWindow和FTDistance参数，应该在服务端检查FTService配置，查看是否存在任何FTWindow和FTDistance受到限制的情况。
3.如果发现FTService配置存在问题，可以尝试调整FTWindow和FTDistance限制，使它们允许客户端访问更多的资源。
4.如果仍存在问题，可以尝试重新启动FTService，看能否纠正任何错误配置。
