When working with the AppDev-Pack you need to use the DQL search to access documents on applications (databases).
This works perfect as long as the application itself has not been fulltext indexed.
As soon as the fulltext index is created DQL queries that worked perfect, start to complain about ...
You are not authorized to perform that operation - error during planning and tree generation
numFieldName >= 5
(Call hint: FTCalls::FTSearchExt, Core call #0)
This problem occurs also for Date and DateTime queries.
Please provide a bugfree implementation where DQL and FT-Index can coexist on an application without interfering each other.
