I have not worked with SSDs, though I've read all the good information that's trickling to us from Denmark. One thing that I've been wondering all along is - what about writes? That is, what about writes wearing out the SSD? How quickly does that happen and when it does happen, what are the

I can't speak to a lot of this - but regarding the servers I'd go with the more powerful ones, if only for the amount of ram. Your index will likely be larger than 1 gig, and with only two you'll have a lot of your index not stored in ram, which will slow down your QPS. Thanks for your

Hello, We're planning to use SOLR for our project, got some questions. So I asked some Qs yesterday, got no answers whatsoever. Wondering if they didn't make sense, or if the e-mail was too long... :-) Anyway, I'll try to ask them again and hope for some answers this time. It's a very
