Lucene newbie needs advice

["Stone, Timothy" <ts...@cityofhbg.com>]

Lucene users,

Lucene looks like the answer to my site-only searches, a robust API and
active user community. I have a rather static informational site, html and
some pdf, coming online; hits may be heavy in the beginning, but drop
dramaticly following opening. 

The general practice of searching the web is known, but search engines and
the technology/terminology of searching are foreign to me and I'm looking
for a rapid, drop in solution, with little customizing at this stage (until
I can come up to speed). I'll be running an Apache Tomcat environment
(really only to enable Luncene).

How much harm is there in deploying the Lucene demo/example, with some "look
and feel" changes and handling for possible redirects to alternate web
search engines?

Also, can multiple Tomcat servers running the Lucene demo share a single
index? Are there threading issues to be concerned about?

My hardware is rather robust at this point. I have two IBM Web servers with
dual 2Ghz XEON processors, 2Gb RAM and dual Gb NICs. The future has these
servers in roles as load balancing proxies in front of a switch, or
switches, managing dedicated web hardware. This is what I'm working with;
capital expenditures are spent.

My configuration plan looks something like this:


Box 1

+--+........>+--+
| Apache1    |  |
|__|         |_Tomcat1   +-+
| Apache2    |  |        +-+ shared lucene index
|  |         | Tomcat2
+--+........>+--+
 

Box 2
 
+--+........>+--+
| Apache3    |  |
|__|         |_Tomcat3   +-+
| Apache4    |  |        +-+ shared lucene index
|  |         | Tomcat4
+--+ .......>+--+



Thanks,
Tim

Sharing a read-only index is not a problem, as long as both machines
running Tomcat can access it.  That is, you would have to NFS-mount the
disk/partition with the index.

Or you can use something like dist or sdist with rsync to send a single
index from the machine where you create and update your index, to all
the Tomcat machines that need to read it when people perform searches.
