browsers I have in mind have a configurable set of attributes which
will be searched for - this is the "limited" set of attributes.
Usually you get more than one entry as a search result - almost all
persons don't build complex filters but search just for "sn=xxx". So these
attributes (locality, description, ...) are used for choosing the right entry.
Clicking on this entry performs a read requesting a second
configurable set of attributes. This could be also all attributes,
of course - including images or whatever.

Hope this helps.
