Pushing the design of swish-e, perhaps.  Seems like more people are 
using swish-e for large collections.  How much RAM are you using?

Did you look at inktomi?  It uses a database that is searchable as it is 

You might also consider writing the output from the spider to a local 
database of some type that allows updating over time.  And then have 
swish-e index that local cache.

You mean the two URLs return the same content?  One solution is to use 
the md5 check to filter those out, although it might be slower and the 
checksums are stored in RAM.

If you mean a different query string returns the same document, then in 
the test_url you can modify the URI object (i.e. set the query string).  
The test_url function is called before tests to see if it's 
see the URL before.

Yes.  You send the spider a SIGHUP and the spider will stop spidering 
and swish-e will write the index.

I've been wondering what to do with my free time.  Oh, wait, I was
saving that for sleep.
