My advice to you is make your own color schemes that incorporate your versions of `Search` and `IncSearch`. But you if you really don't want to do that you could probably do the following:

    if g:colors_name == "torte"
    ...
    else
    ...
    endif

Please note that this is not guarenteed to work as [this is only a standard](http://stackoverflow.com/a/2419692/1924583) and not a sure fire way to see your color scheme.
