[basex-talk] Simple Xquery '(/org)[1 to 5]' was failed in GUI

Hi, I'm using BaseX first time. and using 7.0.1. about 5000 org.xml was loaded into the db in my test enviroment. But I got an error msg instead of the result i want when I was excuting an simple xquery '(/org)[1 to 5]' in GUI: Query: (/org)[1 to 5] Error: [FORG0006] (1 to 5) not allowed as condition type. The xquery '(/org)[position() > 2 and position() < 5]' excuted very well. Thanks, Edward
