Yes, I tried the q=<query>&rows=-1 - the other day and gave up But as you say it wouldn't help because you might get a) timeouts because you have to wait a 'long' time for the large set of results to be returned b) exceptions being thrown because you're retrieving too much info to be thrown around the system

Setting the 'rows' parameter to a number larger than the number of documents available requires that you know how much are available. That's what I intended to retrieve via the LukeRequestHandler. Anyway, nice approach Stefan. I'm afraid I forgot this 'numFound' aspect. :) But still, it feels like a hack. Originally I was searching more for something like: q=<query>&rows=-1 Which leaves the API to do the job (efficiently!). :) The question is: Does Solr support something? Or should we write a feature request?
