#20 better advanced search

[Michael Scheibe]

An "AND" search is required. I defined the CI type as a catalog (say Client, Server, Printer...)
and the room where it's located as another catalog (say room 31, room 40...)
Now I like to get a list, say, of all CI's with type of server anfd located in room 40.
