Index Version Number
Is it possible for a Solr client to determine if the index has changed
since the last time it performed a query? For example, is it possible
to query the current Lucene indexVersion?
Thanks in advance for your help,
Richard

Interesting. Do you know if it's possible to get the HTTP headers with
Solrj?

Grant pointed to one way - the Luke handler.
Another way is to look at the Last-Modified or ETag HTTP headers.
$ curl -i http://localhost:8983/solr/select?q=solr
HTTP/1.1 200 OK
Last-Modified: Fri, 10 Apr 2009 17:40:54 GMT
ETag: "OWZlNjdkN2Q4ODAwMDAwU29scg=="

This info is available via the Luke Handler, I believe: http://localhost:8983/solr/admin/luke/
: In there, I see: version, current, optimized and true information.
See also http://wiki.apache.org/solr/LukeRequestHandler
HTH,
