Hi Michel, I've been good and documented what I learned from the docs discussion in the interfaces wiki. Can you check and correct as appropriate please: http://www.zope.org/Members/michel/Projects/Interfaces/ACPermissions http://www.zope.org/Members/michel/Projects/Interfaces/QueryObject Also, could the case sensitivity of each of the index types (text|keyword|field) be documented in the Wiki? cheers, Chris
