There is no good indexing/search engine for AFS cells.

My requirements are:

1. indexing by the file servers not the clients

2. storage of the index on a per volume basis.  This is
   required so that the index is correct for each readonly
   and backup volume clone.

3. a distributed search service that spans all file servers
   so that a request issued to one file server is serviced
   by all of the file servers that contain relevant volumes
   without duplication of effort.

4. result sets only contain matching items that are accessible
   to the authenticated entity issuing the query.

5. integration with client OS search libraries

Wish list items include:

1. The ability to issue persistent queries that use the
   AFS callback mechanism to notify clients when the
   result set has changed.

2. Automatic generation of thumbnails and other commonly
   accessed metadata on the file server.

I want to implement these capabilities in YFS but I suspect it is going
to be quite a while before that happens.

In the meantime, a client side indexing solution can be used for a
single platform.  The downsides are the network traffic and the view is
only applicable to a single user entity.
