I am indexing a site that has subscriptions to channels.

So consider a Sports channel.
There could be many URLs under this section:
ESPN
TSN
Yahoo Sports

I have data which tells me how many subscribers there are to each of the
above sites.

So for instance, if I had this subscription list:
25,000 - ESPN
10 - TSN
100 - Yahoo Sports

I can easily add meta tags to each of these documents including the number
of subscriptions.
<META NAME="subscription_count" CONTENT="25000" >

Based on this information I could change the default sorts from "swishrank"
to "subscription_count".
But rank is a complicated thing, based on search strings, proximity, title
vs body and so on.

Those are all very valid criteria.
Is there a way to combine all of this?

TIA,
Dave
