Good work Dr. Hipp and thanks for Sqlite.
One question comes to mind when looking at the changes implemented. In
particular..

directory as the original database")

The performance is pretty much the same as using a :memory: database.
Indexes can still be useful on memory databases to speed up queries.
It depends on your schema/data. Try it and see.

As I explained to you a couple of days ago in this post

I'm using MS VS 2005 (SQLite 3.3.9) and having problem re-building the

Any files should be included

I have a reasonable understanding of the PC architecture, and more
appropriately the architecture which the operating system presents to

serial environment.
Bill,
Thanks for the description, thats pretty much how i designed the
index, but with a few modifications. The filesystem becomes the tree
structure which is indexed by a hash of the original document url. It
works like a big hashtable so its quite scalable.

There were a few minor enhancements to the optimizer,

lets say one field has this text "big monster".
