>can you list those as well?
Why? If you are looking for a reference on a particular topic, ask about it. "hundreds of books on... (blah)" isn't useful to anyone at all, unless they really want to learn about the book purchasing habits of some random individual on the internet.

Did anyone forgot: The Art of Computer Programing by Donald Knuth?

xkey mentioned it : TAOCP
Let's say we all have some books on computer languages, other computer oriented issues and mathematical isues. I have to much of them to mention them all here...

I hope not to scare you with this long post. I'm testing Solr (read solar) and it works fine. I have an issue with the DataImport handler, it's set ...
