Before realising that the default SI4T build is against Solr 4.4.0, I had already installed Solr 4.5.1 (dumb, I know, but I hadn't realised it was so fast-moving!). The SI4T documentation says you can "do a build yourself in case you need functionality of later versions of Solr", but I'm wondering whether I can expect any breakage if I run the pre-built jar against 4.5.1 (I guess there's some sort of breaking change at 4.4, but how often do they do that?) (This is unfamiliar tech for me: I'm willing to try it, but I'm not sure if I'd detect subtle breakage.)
Next up - how would I actually set it up. The documentation leaves it "to the reader to mix the proper set of jar files in case this is needed.". So what process should I follow to determine what the correct set should be? Alternatively, if the correct answer is "that's too hard, just install Solr 4.4 and go round", that would also be helpful.
Edit: I'm on Tridion 2011, although the question is really about the process.
