Not all discussed (or even used) Squid-FS:es can support a arbitrary indexing
policy. Squid-FS:es combining storage and indexing (such as reiserfs-raw, my
cffs design, apache/cern style cache, etc) will be pretty much tied to their
own indexing method, as the indexing then is an integral part of the FS.
It is also true that FS:es implementing their own indexing method will also
be pretty much tied to implement their own policy.
Generic Squid-FS:es, where the indexing method is independend of the FS sure
can be made to use a pluggable indexing method, just as the policy can be.
