Technicallly it should be possible, but you need to write another
retreiver spider for the engine knowing how to read the squid cache files
instead of fetching from the web or indexing local files.

The format of the cache files are described in the programmers guide and
iirc there is even a perl module in CPAN for reading these files.

The developer list for the preferred search engine is a better place to
ask I think. There is no modifications required to Squid but the search
engine needs to be slightly modified to know how to read the Squid cache

Each file in the cache contains

a) Meta data like the URL of the file, size, time cached etc. Of this the
search engine needs to use the URL as "name" of the indexed object.

b) The object HTTP headers.

c) The object contents. This is what needs to be indexed.

b+c is the HTTP reply as received by Squid.
