Solr and Javascript Templating (Solr meetup presentation, September 2012)
Here is a copy of the short presentation I gave at the Solr meetup on the 4th September 2012. Read it if you want a really high level view of the cost, performance, and functional benefits of using Javascript templates to create search applications.
One of the live demos has also been uploaded here to demonstrate how a Solr server can be rendered using JavaScript.
For me, the only drawback I can think of is SEO. Anyone tested how JavaScript rendering possibly hurts your traffic from search engines? Bots do render/read some JavaScript, but how much?
Ahh! Good question! Although some clever web crawlers may have JS turned on, its is safe to regard content generated from JS as essentially invisible to most crawlers. So if you are trying to optimise your result pages for search engines, this is not the way to go about it.
