Select and highlight features

[Lawrence Hartpence]

I know this is a very simple question, but I am not figuring it out.

I know how to query a feature and get MapServer to zoom to it.  I have seen
examples where the selected feature was highlighted and other examples where
the feature is highlighted and the unselected features are not displayed.

Could someone explain how this is done.  I am using CGI MapServer.  I will
probably need a fairly thorough explanation.

Thanks!
