⟩ Suppose there is a search spec on BC, and Applet both. explain the execution of this scenario?
This is not true . Actually BC search specification will be replaced by Applet Search specification(NOT appended) and finally you will get the data queried using Applet search spec.
When we set search spec in BC and Applet it will do an AND between the Search spec of BC and Applet. For Exp: Bc level search spec is Name=Vijay and Applet level Country=India then the records display where Name=Vijay and Country=India.
