Thanks for the answers, they helped a lot!

What about searches that try to match exactly but only part of the
title1: "Web Services with Perl"
title2: "Deploying Services on the Web"
search: title:"Web Services"
This seach should find title1 but not title2. Is "text" the correct type
or do I have to use "string" for this to work?
(Yes, I can test this myself but I have so much to learn and test that
it would help if someone can answer this off hand).
And: do you use "text" and perhaps "string" for all the other fields?

Thanks for the hints, I will follow them!
Regarding boosting: this was just one example I found from requirements
in my institution, I am also looking for other ideas how to improve

I don't need cross searching (yet) but I was afraid of starting too many
daemons or is it possible to have multiple indexes with one SOLR server
(like you can have multiple databases with one MySQL server)?
And yes, there will be millions of records, at least eventually.

That would really help, so if someone can remember where to find such a
tool or command please post the info.
To Peter Kiraly: Learning at least some JAVA is on my todo list but at
the moment all I know are scripting languages: Perl best, some Python
and PHP (see my other post on this one).
But perhaps there is a JAVA tool around (the same Peter Binkley
mentions?) that can take a prepared XML (or other text file) and feed it
directly into the index?
