I was really hoping to use this plugin but the uploader forgot that most people using WordPress are bloggers and novices. I'm not either and I can't get this to work. Your instructions contradict each others. First you say Solr Server needs to be running as a pre-requisite. Then you say later it's not required. I took that to mean that you updated your plugin but didn't rewrite your instructions. I have no idea what you mean. I have no intention to use this plugin outside of my website, just internal searching so your paid alternative server doesn't make sense to me when I can run a Solr locally. Problem is, which one? There is the solar for wordpress that you say should be uninstalled (which makes no sense) or Solar 3.6 from Apache. I download and attempted to set up each one with no success. Documentation or walk through is no where to be found. I run XAMPP so I assumed this would be easy. The plugin might work but until a simple non contradictory setup is clearly explained in your install tab, I wouldn't recommend this plugin to anyone.
