Ad hoc designer display column filter queries

[puneet.garg]

Hi,

I am evaluating jasperreports server 5.2. I have couple of queries on Ad hoc designer filters:

- Can we control some available fields and measures not to be allowed to add as filters?
- Can we control some available fields and measures to add as text filters rather always as drop down with all distinct values?
- Can we customize drop down filter values population queries?
- Can queries of  designed reports/views with filters be modified to use indexed ids columns rather dropped filter fields those are non indexed strings?

Thanks in advace for your help.
