Solr the right thing or too big?

Hi there,

we are running a locale website that provides basically informations about events, businesses, classfieds, news etc. in one city.
To make it even more locale, we need to categorize everything by the districts / areas within this city.
I want the users to be able to click on:
old town
And see the three last shops, ads, events, classfieds etc. from the old town.
Clicking on 'all shops in the old town' (shops and old town should be arguments somehow) should show the shops in the old town (surprise ;) ).

At the moment I'm trying it with taxonomies, view, panels.
Problem is: I have on district taxonomy for every CCK type (because of taxonomy_menu - otherwise I'd click on old town and get a chaos of every CCK type.

Adding more content / taxonomie terms adds more complexity etc.
I feel this is the wrong way to go.

How can I make it better?
I experimented around with faceted search now which seems to lead towards the right direction.
But maybe I can't grasp the whole thing yet?
I was hoping that there are some people who already did it or know an example and what to use.

I'd like to add a geographic search later on (show all ads around me within 2km) or some dates included:
I'd like to see what I can do at this weekend, open air with music or sports.

Any suggestens, how I can make my Drupal more user friendly and more (admin) scaleable?

Thank you in advance
Bye, Transmitter
