Re: Should I install 4.x or 5.x? Book recommendations?
I would also suggest to use Solr5, as there are lots of new features. We are using 5.2.1 now, which is pretty stable. 2015-10-23 16:32 GMT-07:00 Shawn Heisey : > On 10/23/2015 12:22 PM, Robert Hume wrote: > > I'm investigating installing a new Solr deployment to be able to search > > about two million documents (mostly HTML and PDF). > > > > QUESTIONS: > > > > A.

Or should I stick with the latest 4.x release? I think the books were covered pretty well by Alexandre, so I won't go into that. I agree that you should use 5.x. Once you get a particular major version deployed, upgrading to a new major version can be challenging. Upgrading to new minor versions is usually pretty easy, so go with the latest version. Additionally, it is highly unlikely that you will see any bug fixes for 4.x. If a serious enough bug is found, a new 4.10.x version may get released, but it will have to be a HUGE bug, without a workaround. I can guarantee that you won't see any performance improvements in 4.x. There will never be a 4.11.0 version. 4.x development is effectively dead. Most effort is focused on 5.x, and some of it is focused on 6.0. There is always the possibility that 4.x might be more stable than 5.3.1 ... but this is a very slim possibility. A lot of effort is spent trying to make sure that all releases are as stable as possible, and frequently, especially when running SolrCloud, the newest version will be more stable than anything in the previous major version. Stability is likely to improve with each new minor release. If 5.x were still at the 5.0 or 5.1 version, this might be different advice, but there have been four minor releases in the 5.x series. Most of the bugs that are inevitable in any x.0 release have been fixed. Thanks, Shawn
Re: Should I install 4.x or 5.x? Book recommendations?
To add: 5.x is NOT a hugely different thing from 4.x. The version update was because of Lucene index versioning issues, nothing to do with core functionality within Solr. So, there really is no reason to hold back from using a 5.x release (any more than there is from holding back from using any latest-and-greatest release of anything).

Re: Should I install 4.x or 5.x? Book recommendations?
http://www.amazon.com/gp/product/B00D85K9XC (kindle version) I love the mixed reviews on that edition :-) https://www.packtpub.com/big-data-and-business-intelligence/instant-apache-solr-indexing-data-how-instant (digital version from publisher). If you join my Solr Resources mailing list at: http://www.solr-start.com/ you should get 50% off coupon in the welcome email (let me know if you do not). Either way, it is a small book, not worth waiting for it to be POD printed and shipped. But really, I recommend you find it in some _other_ way. It is only good as a supplementary material now. And I am too busy to update it as I am working on a much bigger Solr book: http://www.amazon.com/gp/product/1491920149 Regards, Alex.

Hi Alex, What's the title of your book? An amazon link would be useful too. Thanks! Rob On Fri, Oct 23, 2015 at 2:50 PM, Alexandre Rafalovitch wrote: > Definitely 5.x. Lots of new goodies.

Re: Should I install 4.x or 5.x? Book recommendations?
Definitely 5.x. Lots of new goodies. It is true that some of the startup scripts are different and the example schemas could be slightly confusing if following a book, but I think it is well worth starting on a good foot. Just remember, no "collection1" anymore, all cores/collections are explicit. And there are tutorial and reference guide available to help you along. And "Solr in Action" is a great book to purchase. Though, I'd recommend an electronic copy unless you want an exercise regime as well :-) I would say grab my book as well if you just want step by step introduction, but frankly it is definitely out of date (Solr 4.3!) and publisher pushed the price up into the ridiculous territory last time I checked. So, don't buy it. But if you have O'Reilly Safari account of some other ways to get to it, give it a glance too. Regards, Alex.

Should I install 4.x or 5.x? Book recommendations?
Hi, I'm investigating installing a new Solr deployment to be able to search about two million documents (mostly HTML and PDF). QUESTIONS: A. Should I use Solr 4.x or 5.x? My concerns are mostly to do with support. Is 5.x too new to be able to get good answers and advice from the community? Or should I stick with the latest 4.x release? B. Anyone have a good book recommendation? I was thinking of buying "Solr In Action" but it looks like it was published in April 2014 so it won't have any 5.x info in it? Thanks! Rob
