Our Solr system is up now since a few days. You can find it at
http://www.booklooker.de/
I'm sorry we have a german user interface only, but maybe if you want to
try out our system you just can fill out some fields in our search form
and press "suchen" on the right side. We are "book brokers" and maybe
it's not to hard to find out that "Autor" means "author" and "Titel" is
"title". "Stichwort" may be interesting because this means "keyword" and
will perform a search in a "multiValued" field in Solr. One important
notice: there are two checkboxes labeled "gebraucht" (used) and "neu"
(new). Do not check "neu" because this will search in an external
database which is much more slower than ours. ;-)
For the more technically interested I give you some parameters. We have
now about 10.5 million documents in our index, each consisting of 24
fields (you can see why, when you click "SUCHEN" on the left side which
will present you a detailed search form). The index is 2.6G big on disk.
We have two Solr servers running (actually Tomcat server), but normally
just one is active. Our users submit about 200.000 queries per day which
is 2.3 queries per second. Typically this varies from 1.5 to 4.5 queries
per second over the day. Additionally we have about 100.000 "search
tasks" in our database which are processed in the morning hours
(increasing the number of queries per second to 11). The index is
updated once per day on our main server and then copied to our second
server.
If you have any question I'm glad to give you further information.
Thanks to the Solr community for helping us setting up this system!
